Five specific vertical mill operating point analysis

1, stable material bed  Remained stable material bed, which is the foundation bed abrasive grinding roller, the key to normal operation. Material thickness gauge ring by adjusting the height adjustment, the correspondence between the appropriate thickness and between them and the Raymond mill output, we should first find out during the commissioning phase. Grinding efficiency reduces material layer is too thick, too thin material layer will cause vibration. Such as the roll increases, the more fines are generated, the thinner the material layer; rolling reduction, disc material thicker, more material corresponding return, the material layer thickens. Winds from the mill to improve and increase internal cycle, material layer thickness, lower wind speed, reduce internal cycle, the material layer thinning. In normal operation under the bed thickness roller mill grinding roller compacted by not less than 40 ~ 50ram.  2, the control grinding pressure  Grinding pressure is a major factor in mill production, mill grinding efficiency and power of influence. Vertical roller mill is subjected to high pressure by means of the material bed and the crushed material, the pressure increases to increase production, but after reaching a certain critical value does not change, the attendant increase in pressure is to increase the power, resulting in unit energy consumption increases, so the appropriate roll to yield and energy both. This value depends on the material properties, particle size and volume of feed. When the trial production grinding pressure to find a suitable and reasonable wind pressure can form a good internal circulation, so that the material layer on the disc proper, stable, high grinding efficiency. In the production process, when the wind ring a certain area, the wind speed is determined by the amount of wind. Corresponding relationship between the production process and the ability to ensure the grinding effect.  3, to ensure a certain degree of the grinding temperature  Vertical mill is drying and grinding system, a mill drying temperature is a measure of whether the normal operation of the integrated indicators. In order to ensure good drying of raw materials, the grinding material moisture content of less than 0.5%, the general control of the mill outlet temperature at 90 ~ C or so. If the temperature is too low then the finished water large, so that the grinding efficiency and reduce separator efficiency, it may cause condensation collecting system; if too high, indicating that the flue gas humidification cooling is not enough, also affect the collecting effect.  4, reasonable wind speed control  Vertical mill stream driven mainly by material circulation. Winds can form a reasonable good internal circulation, so that the material layer on the disc proper, stable, high grinding efficiency. However, the amount of wind is determined by wind speed, and wind and the amount of feed is linked, such as feeding a large amount of air flow should be large; otherwise reduced. Fan unit affected system resistance can be adjusted by adjusting the fan valve. Drop mill, feed mill negative pressure, the negative pressure can reflect the amount of wind mill size. Pressure drop, negative pressure indicates wind speed, air volume; otherwise, the corresponding small amount of wind speed. These parameters are stable, says the amount of wind is stable, thus ensuring the stability of the material bed.  5, control raw material fineness  Fineness of raw material by a separator speed, air volume system, the mill load and other factors. In the air volume and load unchanged, can be adjusted by changing the rotational speed manual fineness, when adjusting a maximum increase or decrease 2r / min, resulting in mill vibration over the General Assembly to increase even tripping.

How to Configure an Efficient Sand Production Line?

Sand production line is composed of jaw crusher, impact crusher,sand making machine, efficient tertiary crusher, vibrating screen, sand washing machine, belt conveyor and other devices. Faced with the situation that natural sand is less and less, we should produce artificial sand to satisfy the increasing market. It has features like good shape of final products, high sand rate, regulatable fineness and low production cost. The artificial sand production line has a complicated structure because it is composed of many machines. So it is easy to have problems during production, among which the jamming problem is the most common. The reason of jamming is too fast feeding or inappropriate transmission device configuration. 1. We should clean the air supply outlet timely and regulate the transmission device when jamming happens. 2. Too fast feeding of materials also will cause jamming of sand production line. We should know that too fast feeding will increase the machine's load and easy to cause jamming. During feeding, we should pay attention to the electricity, namely the deflection angle of ammeter pointer shouldn't be too large. If the required electric current is surpassed, it means the electric motor is overloaded. If it is overloaded for a long time, the electric motor will be burned. In this situation, we should reduce or shut the materials door or change the feeding style. The Working Process of Sand Production Line Is as Follows: First, the rocks are coarsely crushed by crushers, and then the coarse materials are transmitted by belt conveyor to tertiary crusher and receive the second crushing. The products after tertiary crushing can be divided into two kinds: the qualified sand will enter into sand making machine, while the unqualified sand will return to tertiary crusher. So why should we configure the high-performance sand production line, and will it definitely improve its quality and quantity? The sand production line has high automatic degree, low functioning cost and high reduction ratio. So the good configuration of it will definitely bring good economic benefit. The general process is (stock bin) - feeder - jaw crusher - impact crusher - vibrating screen - (finished products).

Raymond Mill factory technician installation required

SBM machinery specializing in the production of ore crushing equipment, including Raymond mill, high pressure hanging roller mill and the ultra-fine grinding series of products are widely used, high efficiency welcomed the consultation visit. Here to talk about the structure of Raymond mill use. Raymond Mill powder confidential by the host, analysis machine, blower, finished cyclone, plumbing fixtures, electrical and other components. Where the host from the rack, inlet volute, blade, roller, grinding ring, casing and motor. Raymond is the seventies of last century a milling machine imported from abroad, has been widely produced in the country. Raymond is mainly used for marble, limestone, calcite, etc. Mohs hardness of not more than 7 280 kinds of materials, mining, chemical milling, processing, product fineness of 400 mesh or less arbitrary regulation, Raymond from the appearance look like a steel container upright with inlet, outlet, central feed inlet. Raymond lower part of a motor driven internal grinding disc rotation will need to stick with the material crushing or grinding mill, through the air inlet of the wind blowing the finished material, inside the upper part of the mill with a separator, the thickness of the powder can be separated and then via through Raymond wind from the outlet out of the collection. Raymond mill is mainly composed of milling systems, analysis systems, dust removal system components, from the granular powder to be processed into a shape, fineness uniform, through screening rate, wear parts and long service life, easy maintenance, low dust, small footprint, complete sets of strong, low investment and high return. Raymond application will be high, but reasonable installation of Raymond also had points to note: customer after installation Raymond, Raymond found in the normal course of its production, and which is not expected What good, or in use for some time, the discovery yields are low, so manufacturers often complain to buy a bad product. SBM Mining Machinery Co., Ltd. As a professional manufacturer of milling machines, the mood of such customers understand that, but also patiently explain carefully to our customers, exactly under what circumstances will it be possible to Raymond mill manufacturers affect work efficiency , we hope to help customers and friends. First, the ore type and composition The composition of a variety of ores are not the same, different hardness, wear resistance are not the same, the impact on the grinding efficiency is also very large. If the composition of the ore, the mineral particles larger structure is relatively crisp, that this mineral is easier to grind. But the mineral particles smaller structure density and hardness is larger, the mineral is more difficult to grind. Generally, the material particles moderate, relatively crisp material are easy to wear materials, because as the particle reduction, fragile surface material is relatively reduced speed to produce qualified fineness will slow down. Accordingly, coarsely ground finely grinding efficiency than high technology. Second, the performance of the mill equipment Technical performance and service life of wearing parts mill mill itself, but also on the efficiency of the grinding is a certain influence. Third, manual operation Because the mill itself is more complex structure, during operation, must be in strict accordance with the instructions to perform, otherwise, is not a small mill will affect the stable operation of the finished product efficiency, etc., so that not only reduce productivity , the wear and tear of Raymond also will be a big loss.

The new mill with the old-type milling machine which features compared

Applications mill is widely used, mainly used in building material, chemical industry, metallurgy, mining, abrasives, refractory, ceramic, steel, thermal power, coal and other industries. Work process mill is mainly driven by rotation of the central shaft reducer, the upper end of the shaft is connected to plum frame, rack mounted roller device and form swing pivot. Grinding roller not only rotates around the central axis of rotation, but also around the grinding ring revolution, roller itself due to the friction and rotation. Under Plum rack mounted blade system, its position in the lower end of the roller, roller blade and process with the transfer between the material thrown feed roller and grinding ring, forming a litter layer, the litter layer by grinding outward centrifugal force generated by the rotation of the roller (i.e., pressing force) of the material is crushed, thereby to achieve the milling purposes. With improvements in technology, and now the new mill, compared with the Raymond mill has unparalleled advantages, apply a number of national Latest mill patented technology, innovative design, reasonable structure, small footprint, power consumption low, long operating life, and the vulnerability of low cost, and high cost. The new mill mainly by the host, blowers, ultra-fine analysis machine, the finished product cyclone powder, a bag filter and connecting duct piping and other components, according to user needs can be equipped with elevators, storage silos, control cabinet, to powder, crusher and other auxiliary equipment. In micro-grinding grinding chamber, roller assembly by hanging on the cross arm shaft roller hanger, roller blade knife hanger with the spindle and the fixed link, the pressure spring by pulling the lever firmly pressed roller bearing chamber On the outer end of the boom to the cross arm axis for the support by spring pressure roller grinding ring tightly pressed against the surface of the inner circle, when the motor is rotated by the drive means, mounted on the turret on the shovel blade and roller synchronous rotation of the roller in the inner peripheral surface of the ring rolling mill at the same time rotate around its own analysis of machine driven by the motor gearing analysis impeller rotation speed of adjustment of its analysis machine determines the fineness of the powder. The new mill's working process is: the material after being crushed by the elevator into the storage hopper, then fed from the feeder evenly host grinding chamber, after the shovel blade into the grinding roller and grinding ring between Laminated rub, fans will be blown into the grinding room, blowing the powder into the analysis machine, be winnowing, reach the fineness and regrinding, qualified powder into the air the finished product cyclone powder collector, and air separation from the discharge port is finished. Material containing some water, would produce a certain moisture grinding, and the entire pipeline due to the tight seal is not absolutely certain external causes gas is inhaled, the system circulating air volume increases, in order to ensure the mill work under negative pressure, the excess amount of wind After entering the baghouse purification into the atmosphere. Compared with the old-type milling machine, apply the configuration of the new mill has a great advantage: it can play a balanced use of supercharging pressure spring and damping effect can play smooth elastic coupling. The machine uses the lever principle, the symmetrical roller assembly with a horizontal rod connected together by spring, when the bulk material posing a top roller assembly, the radial force of the spring rod passed through the plane of symmetry roller assembly to balance, under this condition, the overall force point devices and other products to improve compared to about 40%; and the elastic coupling means is to reduce the vibration and noise, to avoid resonance. Accuracy can be improved with the election powder and products of high-density separator impeller. Practice shows that in the speed remains unchanged, increasing the density of leaves can increase the fineness of the finished product, in other words, in the case of fineness do not need to change, high density impeller impeller speed than the low density, reduced airflow resistance, under the same power of finished production increased more than 50%. Equipped with high efficiency centrifugal induced draft fan. On the traditional machine is equipped with a prismatic blade efficiency of only 62%, while the impeller and blade are both stamping induced draft fan energy efficiency of over 85%. Convenient impeller adjusting device. Size of the gap separator blade end of the housing also affects the fineness, this patented technology enables quick and easy adjustment of the gap size. The unique design of inwardly inclined duct, ensure 迸 into the inlet socket shell material can be smoothly fall within the mill along a ramp.

How Raymond mill power computing

Since the particle size of the fine ore particles become mechanical strength is increased, it becomes difficult raymond mill, and ultrafine Raymond process under control poor, low energy conversion efficiency, so fine grinding and ultrafine grinding lower power consumption increases rapidly. At present, industrial enterprises need to be resolved under the fine grinding and ultrafine Raymond power of computational problems. The following three-pronged approach to calculate the power consumption of ultrafine Raymond. A known standard ore work index, can be measured by grinding the ore test work index determination Under the same conditions, with the same ground Raymond were the same weight of standard test ore and minerals, to find out from the sieve analysis curve them to the mine and the product. Raymond used the same ground under the same conditions the same quality of the ore consumed two functions should be equal. Second, the doctrine of presumed power by the area under different crushing ratio Raymond in the same models, with the prolonged grinding, crushing ratio increases, the power consumption increases. With the in-depth study of the power law, the existing power doctrine can also find new uses. Third, computing power Raymond Several power school, only Bond's original power formula is used to directly calculate the grinding power, because the power consumption of the original Bond formula, feed particle size and particle size sieve analysis can be measured, and Bond work index, can be measured Bond predetermined way, so Raymond grinding power required can be directly calculated. If you want to reduce the cost of Raymond, only to solve the above three problems consume work, it can greatly reduce the mechanical consumption and wear, thereby reducing the cost of production fundamentally.

Vertical Dynamic Design Raymond mill

Before establishing vertical Raymond mill dynamics model to the analysis of the problem analysis program design, therefore, first introduced digital design work Raymond boundary conditions. Air spring as an important boundary condition SBM Raymond mill machine vertical kinetic model, which directly affect the dynamic behavior of the stiffness characteristics of vertical Raymond, therefore, the calculation of the air spring vertical and lateral stiffness characteristics is our first content analysis and calculation. The air spring vertical and lateral stiffness characteristics obtained, on the one hand to select a different model for the design of vertical Raymond mill air springs provide the basis for the other, for the establishment of virtual prototype based on vertical dynamics Raymond mill isolation model provide important data. Spindle is an important part of a vertical wind in front of Raymond, whose dynamic characteristics have an important influence on the dynamic characteristics of vertical grinder machine. In the course of spindle bear incentives, bearing displacement constraints and other effects from the upper and lower eccentric, its force complex and large amount of deformation, and therefore it needs to be treated as a continuous elastic body during operation. Application of multi-body dynamics theory, the spindle treated as a continuous elastomeric method is to establish the modal neutral file containing its dynamics by the finite element technique, and then replaced by rigid spindle modal neutral file set up as a flexible shaft style disaster Raymond rigid body dynamics analysis together, resulting in more accurate dynamic simulation results for vertical roller mill body. Raymond vertical dynamics of the body is the focus of this article. Understanding the dynamics of vertical Raymond dynamics we have broken grinding media so as to control the media crushing force, get the desired effect of fragmentation is very important for this purpose. Here, the application of mechanical system dynamics analysis software ADAMS Raymond were established vertical rigid body dynamics model of the whole body and rigid disaster kinetics in model, simulation analysis vertical Raymond body dynamics in both models and compare the simulation results. The results with the vertical Raymond dynamics mathematical derivation formula to compare the body to verify the correctness of the results of dynamic simulation. Raymond is generally believed that the body's dynamic behavior of vertical stiffness is subject to vibration, vibration frequency, affect eccentric mass, the mass of the excitation frequency and eccentric together to produce the exciting force, therefore, be considered separately here Isolation Raymond impact on the dynamics of vertical machine center of mass at the lower edge of the stiffness and the excitation frequency. From the crushing force theory, have an impact on material crushing There are two important parameters, both amplitude and force force force-frequency, vibrating crusher theory that high frequency low amplitude force can achieve better crushing effect. Therefore, the establishment of a vertical body dynamics model of Raymond, at the bottom of a vertical cylindrical chamber Raymond add more balls and more short cylindrical dielectric medium, motion characteristics of the medium and medium to generate a force amplitude and force force Frequency and these forces during operation Raymond affect the body of vertical dynamic behavior. Crushing force of a final decision in the media material. According to the simulation results of the media analysis of the material force force force frequency and amplitude, the establishment media force parameters and vertical contact Raymond body control parameters, medium parameters and broken ground force between material properties, is formed by legislation Raymond mill type control parameters to obtain the parameters of different media and then crushing force set specific material broken grinding process according to the material properties.

Barite Raymond Mill

Barite powder is a kind of important inorganic barium-containing mineral raw materials, there is a big difference between the nature of polymer materials, the lack of affinity for its application in the field of polymer materials is limited. To further improve its performance and broaden its applications, must barite powder surface modification treatment. This paper discusses the method of Raymond mill barite surface modification and application, in order to promote barite powder application development. Powder surface modification technology in China in the twentieth century, 80 years before the technology developed. At present, the domestic non-metallic mineral ultra-fine powder of the increasing demand and development, in which the kaolin, calcium carbonate, talc, graphite powder modified more research and application development, but a change of barite research and application development is relatively small. Study abroad barite powder surface modification of the twentieth century began in the 1970s, but in our late start. Barite has a wider industrial use and deep processing of high value-added, and therefore, should be modified and applied research and development of strong barite powder, barite expand the application fields. Barite is an important mineral containing barium, with density, chemical stability and thermal properties and other characteristics, and its main industrial application areas are oil and chemical industries. In the oil industry, mainly used for oil and gas drilling mud weighting agent; in the Raymond mill industry, with barite as raw materials for the manufacture of various chemical products containing barium, such as barium carbonate, barium sulfate, barium oxide, lithopone (lithopone). In the paint industry, barite powder filler may increase the film thickness, strength and durability. Lithopone white pigment used in the manufacture of paints, indoor use than zinc white, lead white has more advantages. Paint for industrial use of barite desired particle size 2μm content and whiteness greater than 90%; in the rubber and plastics industry, with barite as filler, can improve the rubber and plastics hardness, wear resistance and resistance to aging. Because barite has a special character and cheap development costs, they are increasingly subject to people's attention. The development of modern industry, the barite purity, whiteness and particle size have put forward higher requirements. Thus, with the deepening development of science and technology and research, more performance barite will be revealed. Barite deep processing such as superfine splintered, purification, surface modification, not only can broaden the application areas, and better economic returns, there is a greater demand in the domestic market. However, inorganic mineral powder material with an organic polymer in the chemical structure and physical form there are significant differences between the two different surface properties, leading to its compatibility and affinity have a greater difference. When the barite used as a filler, is difficult to uniformly dispersed in an organic polymer and affect the mechanical properties of composite materials, and difficult to play functionality, surfactants and other fine features and small size inorganic fillers. Therefore, barite powder surface modification, you can choose a suitable surface modifier applied to barite, improve physical and mechanical properties of the modified materials, so that barite powder have a wider application.

Quarry Crusher has been widely used because its easy operation

At present, the crushers are widely used in phosphate. The Quarry Crusher is pressed down upon the fixed jaw plate by the movable jaw plate periodically and it will clamp some of materials to be crushed. The two jaw plates are rectangular. The current Quarry Crusher can be divided into the easy swing and complex swing according to the swinging forms of the jaw plate. The cone crusher can be divided into the acute steep cone for coarse crushing and the tilt gently cone for medium crushing and fine crushing because of different form of movable cone and fixed form. The roll crusher belonging to this category can be divided into the smooth roll surface and the tooth roll surface. The ore is in the central crack of the two opposite rotating circular roller. Recently, most Quarry Crushers are universally used in phosphate. Therefore, here we mainly introduce the Quarry Crusher. The Quarry Crusher is generally used for coarse crushing operations. It can also be used for medium crushing for the relatively small ore particle size in the small and medium phosphorus processing plant. The most commonly crusher used in the phosphorus processing plant is the Quarry Crusher with form of simple swing and elbows plate. The users must carefully check the Quarry Crusher if its various components are closely linked, if there are shedding phenomenon and the lubrication conditions of the lubricants before it is started. After starting the Quarry Crusher, the first thing you should do is starting the motor. Waiting for a chance to start other parts after the motor working for some time. In this way, the parts of the machine can avoid burning out because of a sudden start. When the machine is in operation, the staff can not clean and repair the machine to ensure security.

Development of Building Sand Is Inseparable from Crushing Equipment

Sand is one of the necessary building materials in building industry. However, with the exploitation of resources, sand has become scarce resource. Cone crusher, sand making machine and other crushing equipment can process ore, river pebble, tailings, slag and other materials into sand, thus satisfying the demand of construction projects. Along with continuous development of building industry, the demand for sand is increasing significantly. However, the scarcity of natural sand forces us to find another way-artificial sand. According to the estimation of relevant departments, the annual amount of building sand in China is growing continuously. Currently, most regions in China use natural sand. But the natural sand is kind of local resource and cannot be regenerated in a short time. With the development of infrastructure construction and environmental protection, in many areas of our country, the number and quality of natural sand decrease gradually, or even some regions restrict or forbid to exploit natural sand. The contradiction between supply and demand of concrete sand is prominent. And the sand price is also higher and higher. In the peak period of sand using, there are even no sand available, which not only makes the endless chain of resource and environment incomplete, but also affects the progress of construction projects. In addition, along with the rapid development of concrete technology, the strength of construction engineering is increasing. Hence, the technical requirements for sand is also higher and higher. The construction of high-speed rail and highway needs continuous sand, hence, developing new energy and using artificial sand are imperative. At this time, the crushing equipment and sand making equipment come in handy, which play significant role in manufacturing of artificial sand. China has a large number of metal and non-metallic mines. In quarrying and processing processes, it will generate 40% to 60% of tailings. Without reasonable utilization, these tailings waste resources, occupy land and result in environmental pollution. But, these tailings can be made into artificial sand after having sorted and processed by cone crusher and sand maker, which not only solves sand resource and environmental pollution, but also improves utilization rate of resources, thus forming comprehensive benefits.

Raymond cyclone characteristics

Raymond centrifugal separator is the most common cyclone, cyclone characteristics are as follows: (1) The cyclone itself has no moving parts, simple structure, no special requirements of ancillary equipment, it is less investment in infrastructure, manufacturing and installation of. (2) management is simple, continuous operation and easy maintenance small operating costs, low power consumption. (3) can withstand higher temperatures, it can be adapted to meet the current industry the discretion of the physical properties of various temperatures operating system has no special requirements. (4) cyclones can fit a wide range of particle concentration 0.01-500mg / m3). (5) the particle size of wide adaptability, for more than 5um particles have a good settling effect. (6) as a field separator front device, but also as a coalescing filter rear devices. (7) the impact of fluctuations in gas equipment for dust removal and greater resistance required to deal with the amount of gas is stable, the discharge valve does not leak out. (8) does not apply to the processing Lai cyclone dust, the high moisture content of the dust, and corrosive dust. Many factors affect the performance of raymond mill cyclone, and the situation is complex, object-based situation and operating conditions is an important aspect. Generally, the particle density, particle size large, high-speed imported gas and dust concentrations higher circumstances are conducive to separation. But there are some factors that affect the conflicting pressure drop and separation efficiency of such imports in favor of higher gas velocity separation, but too high lead to increased eddy, but not conducive to the separation, a sudden increase in pressure drop. Thus import gas velocity is preferably in the cyclone is generally maintained within 10-25m / s range.

Sand Washers can Be Applied in Countless Fields

The sand washer manufactured by our company has wide range of applications in the industries of mining, gravel field, building material, transportation, chemical engineering, water conservancy and hydropower and concrete mixing plant. After they are crushed and ground into tiny materials, the initial bulk stones are piling up and waiting to be transported to different destinations that need them. These crushed materials will still need to be washed which is completed by using China sand making machine. How many processes are there for the sand making machine to be used? Here our experts will list most of them. When there are bulk barren rocks mixing among the minerals, the sand washing machine will be needed for the slime removal process of the fine grains. When there are not so much in common about the electability of some natural slurry and ore blocks (such as floatability and magnetism), we can get good beneficiation effect after separating sand and slurry from the minerals. When the silt content of the sand and stones is too much, the blocking problem will happen to the crusher, screen and the opening of the ore storage bin, which will result in the production stagnancy. In this situation, we can use sand washers to solve this problem. When minerals are selected through the photo-electricity magnetic separation process, it is not easy to tell the good minerals and bad minerals influenced by the sludge on the surface of the minerals, which will decrease the effect and efficiency of beneficiation. In this case, the sand washing machine is needed.

Raymond duct blockage Causes

Raymond mill in specific production use, circulation duct occasionally clogging, which is to be shut down promptly remove material and check the cause of duct blockage, can continue to be material mill production after overhaul. The main factors that led to its failure appear, allowing you to find the right cause of the disease. Below we explain SBM machine on the following three points under blockage causes. 1, Raymond baghouse not functioning also cause Raymond duct blockage Bag filter is mainly used in the recovery cycle air volume increased airflow while removing dust particles in the air flow, will increase the amount of purified exhaust air from the plane, when the baghouse dust can not be normal operation, a lot of dust particulate material easily accumulation in the duct is formed, so as to cause Raymond circulation duct blockage. Therefore, to promptly stop to check baghouse role in ensuring the normal operation of the bag filter. 2, the fan power shortage due to insufficient air flow generated is normal material flow in the duct can also cause material accumulation phenomenon. Material under the action of the blower along the circulation duct for transmission, so to maintain the normal operation of the blower, the blower can not appear the wind is too small to transmit the motion of the material in the overhaul to keep Raymond rated working voltage of the normal use of power and in order to maintain a stable and lasting work of production equipment. 3, Raymond feed inequality is a major factor causing circulation duct blockage Too little will cause too much material Raymond grinding insufficient, finished powder can not be in effect along the circulation duct blower discharge, increased workload blower, resulting in the accumulation of powdered materials generated in the duct, eventually leading to the air duct blocked. Therefore, to ensure that when Raymond feeding feeding continuous and uniform, to avoid air duct clogging.

A channel plate is provided between the conical cap and polishing material, protecting impeller from wearing. In general, there are three main formation types of weathering sand making machine ,as follows: First, mechanical weathering sand. It is due to changes in temperature and water and salt state changes in rock gap. Second, chemical weathering sand. Oxygen and water solution not only makes the surface near the rock breaking, and makes their chemical composition change, this is the chemical weathering. Through chemical reaction make those unstable minerals in the surface conditions to be another new mineral (to adapt to the surface environment). Third, biological weathering sand. As the creature have physical and chemical properties, so biological weathering sand is the merging of above two. And it often comprehensive effect appear. The existing stone mill is insufficient in the processing of weathered sand capacity. Because they more use the mixing of crushing and conveying equipment, if weathering effect is obvious, they directly fine tailings after intermediate crushing. While the match has high requirement on accuracy and waste time, efficiency is also comparatively low. Traditional crushing theory have lower control on the particle size so the capacity and power consumption did not reach the high optimization and still need to be improved. As a leader in sand maker industry, according to the research of weathered sand, standard sand and building sand, SBM Machinery Limited company accumulates years of impact crusher's development experience, create professional 5X series high efficient impact crusher, which introduce Germany advanced mining machinery engineering technology reach crushing, washing and grading simultaneously, product qualified gravel aggregate products one-time and be focused in market by its high utilization rate.
