Faced with the deployment of national modernization work, our crusher industry usher in a new development opportunities. On the current situation, many large-scale construction projects, companies generally do not bear all their construction tasks, and more inclined to put the basis of aggregate production transferred to some scattered sand and gravel producers, so not only saves costs and save time, making capacity of SMEs supporting industry modernization has increased, especially in the green level, China has invested vision has conducted some adjustments.
For the next few years to bring national policy adjustments development opportunities, many companies have started to change crusher R & D direction, the introduction of Quarry Crusher , jaw crusher, impact crusher, vertical roller mill, mobile crushing plant and construction waste processing equipment, such as efficient equipment, which is both environmentally friendly, ecology, perfect fusion of low carbon concept, but also for the green development of mining, construction and other fields to provide a strong technical support. Low carbon environmental protection, high-tech crusher industry driven by national policy, expanding market demand for crusher equipment, crusher industry to promote innovation started. China's urbanization, industrialization launch speed of new rural construction and accelerating the construction industry, high energy consumption, use of power has become a hinder efficient and low economic development. Thus, vigorously carry out environmental, ecological, low carbon concept of green building, research and development and efficient crusher, building materials industry has become the core concept of thinking.
"Twelfth Five Year Plan" low-carbon development strategy, reflects the development of the law of the crusher industry should be based on research and development of green technology as a precondition, Quarry Crusher enterprises should focus on improving the scientific and technological content to enhance environmental benefits and energy, in order to improve their own R & D competency-based same time, through the introduction of foreign advanced technology, with the domestic institutions of higher learning to establish research bases and other ways to improve the overall quality of products, and promote value-added services and products, which may well be an opportunity to adapt to the full development of their own way, also led the industry to keep up with the pace of the times, and efficient development.
China crusher Network noted that since the 12th Five Year Plan, a number of favorable policies to stimulate the country, not only to deepen the transformation of energy-saving crusher enterprises, but also for the industry to carry out the supply of a broad platform, our crusher industry has also undergone a change, the new Crusher emerging toward large-scale, intelligent direction,
Sand Making Machine functional diversification, expanding the scope of application, and then towards the hydraulic cone crusher technology, multi-cylinder cone direction, it can be said that China crusher manufacturing industry is undergoing new changes. I believe that China crusher industry to adapt to the development of low carbon environmental protection laws, while technological innovation as the driving force, further promote the whole industrial system of environmental projects started to shape the future of the green market.
Enhanced crusher industry's core manufacturing capabilities
Crusher, conveyor, grinding machine is the most common use of the mining machinery industry, the most frequent equipment, raw materials and reuse its waste screening, processing, separation has an important role in the foundation. According crushing principle and output requirements are different, there are a variety of models Sand Making Machine. In the widely used coking plant, sinter plant, ceramics factory, glass industry, metallurgy and other departments, the crusher industry has an annual business to join, because the mechanical process is simple, large output, the industry is subject to inventory digestion and technological innovation. Our crusher industry experienced industrial cluster effect for many years of accumulation and the need to innovate to break Bureau, need to form a leading enterprise of points need to enhance the role of guiding investment and financing, to improve the current plight of the industry.
The most prominent of the crusher industry, the problem is that at this stage of market competition is weak, small-scale industrial economy, innovation ability, and so the market is not obvious enthusiasm. To address the current state of development, Sand Maker enterprises to do the overall planning, so that China's equipment manufacturing industry to the "high-end manufacturing," development and enhance the industry's core manufacturing capabilities.
First, to improve the overall quality of industry, the need to cultivate the market a number of large crusher enterprises, promote restructuring of state assets, to invigorate the market economic factors, integration advantages of resources, promotion of investment and financing. Large state-owned capital to promote the advantages of industrial concentration, help in some key areas, such as non-ferrous metals, steel, petrochemical and other industries to form industrial advantages, and make some with independent intellectual property rights, competitive businesses get more support. In terms of attracting investment, crusher industry should focus on projects and new industries, focusing on promoting rational adjustment of industrial structure of machinery and equipment.
Second, improve self-innovation capability of enterprises. Enterprises have sufficient technical support after the foundation, should enhance the clustering effect, greater technological research and development projects, change the development model, to obtain the corresponding value-added technology, and the courage to break the existing technology, innovative new market value.
Again, more established characteristics Industrial Park, formation mechanism, on innovative models. Special Industrial Zone is to enhance the overall quality of an important industrial platform. Crusher industry's core manufacturing capabilities as a platform needs a balanced, harmonious development, the status quo in order to reduce overcapacity crisis and shrinking profit margins. The park to be market-oriented operation, enterprise management, enhance the level of economic growth, parks, expand the economy.
China crusher network that the development of the industry needs to be the core manufacturing capabilities to support the industry still breaking as a starting point, to strengthen the development advantages, foster industrial park, to expand the industrial new markets.

Vertical roller mills versus ball mills
Around 110 years ago a Danish engineer, M. Davidsen, patented a pioneering invention in France which involved a tube mill with a charge of steel balls or flint pebbles for fine grinding of sand or cement. F.L.Smidth acquired the rights to his patent and started selling an improved version of this mill all over the world. For the cement industry the ball mill was really an epoch-making breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding. Over the last three decades vertical roller mill has become the preferred mill for grinding of raw materials. The grinding efficiency of the vertical roller mill combined
with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. However, despite these benefits, applications of the vertical roller mill for cement grinding are less prevalent. The two-compartment ball mill operating in a closed circuit with a high efficiency separator is thus still the most preferred arrangement for new cement grinding installations although the vertical roller mill now has emerged as a viable alternative to the ball mill system and has increased its share of the market for cement mills over the last decade. There are a number of explanations to this situation, related to issues like cost and ease of operation, cost of installation, cost and ease of maintenance, Quarry Crusher, versatility, etc.
The following presents a comparison of the two mill systems with reference to these issues. The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the majority of
the particles in the bed are considerably smaller than the thickness of the bed. It is thus necessary that a stable and consistent grinding bed is formed between the rollers and the table of the vertical roller mill, able to sustain such a pressure without the material being squeezed away from the pressure zone.
A stable grinding bed is usually easily obtained in raw material grinding in a vertical roller mill with a high efficiency separator. However, in cement grinding it becomes more difficult to form a stable grinding bed as
· cement is ground much finer than raw meal
· the feed to a cement mill is often completely dry and is significantly more difficult
to grind than raw materials
· requirements to the particle size distribution of the finished product are much
more strict when grinding cement than when grinding raw materials

Vertical roller mill finish grinding program in cement
For the vertical roller mill cement solutions RRB curve to flatten, the providers had been improved sorting gear, the main measure may well be the original classifier has changed effective classifier cage wind blades. High efficiency separator, a clear separation, that is characterized by the fineness of one's distinct surface region by adjusting the rotor to attain high surface area
Item requiring larger speed. Particle size distribution impacted by wind, decreasing the level of wind, escalating the concentration would decrease separator efficiency, thereby minimizing the worth. Cost-effective match amongst the two may be in a position to make a completed solution to meet the needs.
Denmark Smith Company beneath its regulatory OK range Vertical roller mill cement overall efficiency technique, summarized the principle recommendations listed in Table 1 from a sizable number of production practice. That's undoubtedly, when the cement Vertical roller mill might be the comparable surface location, increasing its height gauge rings, or improved stress grinding rolls, both precisely exactly the same effect, will bring about the completed cement
Wider array of particle size, the compressive strength of smaller, standard consistency water demand decreases. But the boost within the quantity of wind mill, the effect may very well be the opposite with the former conclusion, the integrated use of these manage implies, can regulate vertical cement mill functionality inside a wide wide variety, within the current usage, the particle size ratio of milling a whole lot extra close
Management, strength of cement has reached or exceeded the ordinary ball mill grinding of cement.
3 Common vertical cement finish grinding mill production instance LM56.33 3.1 Hubei Yadong Loesche vertical roller mill cement finish grinding system Hubei Yadong Cement mill method to become spot into operation in July 2007, after about a month of adjustment, namely access to normal production. September operating cost, which amounts to 88.1, as well as the production and consumption are far far better than

Cement grinding process standard technical measures
This makes the local cement production enterprises are facing severe challenges. The new standard for the quality of cement made more stringent requirements, especially cement fineness and particle size distribution, the majority of local vertical roller mill technology obviously can not meet this requirement must be cement grinding process and equipment innovation, in order to meet the cement strength standards. Strength properties of cement particles of cement strength of cement paste depends on its chemical composition of mineral composition and physical state, from the perspective of cement grinding, cement particle characteristics have a greater impact on the cement hydration process and strength. Fineness of cement coarse affect the strength to play with cement fineness sieve residue and specific surface area, said local cement companies to use more than a square hole sieve sieve residue and percentages hereinafter referred to control. In contrast to foreign cement is much thinner, I sieve sieve over a cement accounts that I cement fineness sieve sieve almost no remaining. vertical roller mill reasonable particle size distribution of different cement grinding cement grinding system of particle size distribution is different, the same clinker grinding when conditions change, and its particle size distribution also changes, which directly affect cement performance. Reasonable particle size distribution of cement clinker and make active in admixture can be fully tapped and utilized. The particle size distribution of cement production control targets were always listed cement companies. Activity in the full use of cement and improving the performance of Silicon considered existing silicon of ordinary cement fineness of cement particles may have one not involved in the growth process of silicon strength, vertical roller milltoo coarse particles can not fully hydrated, since only the silicon the role of micro-aggregate of particles too fine agglomerate or increased water demand of cement, which causes an increase in the porosity of the alkaline, silicon strength is lowered, which mix the particles in the fully hydrated, to increase the strength of age no effect. So cement particles must have a reasonable particle size distribution, in order to obtain the highest strength.
The reason the oil spill caused by mill
Occur in the course of mining machinery and equipment will always inevitably some problems, one of which is the oil spill equipment problems are often encountered. vertical roller mill appeared spill how to do it in the course of their work?
Mill leakage problems abound. This phenomenon seems to be a very common problem, on the causes of this problem, which we asked in detail about the vertical roller mill's R & D staff, they are so interpreted. Many parts of the mill employs advanced seal device, resulting in leakage of the main reasons, refueling time, high pressure will cause the seal ruptured oil gun, as well as seal damage. Or the oil viscosity is too large, stagnant oil pump will cause bearing in oil fever.
When purchasing mill, with instructions, our label instructions for oil viscosity has specific requirements, so be sure to refuel in strict accordance with the instructions.
In addition, mill for ultra-fine powder materials processing equipment, there is the inevitable dust; but if too much dust in the production process, we should deserve attention. Cause mill dust precipitator is often did not play very good effect, then one of the most fundamental reason is: the initial layer of the bag surface is not enough; bag breakage; bad bag assembly. Only protect the baghouse, so in order to do a good job of collecting vertical roller mill production line work.
After a year of development in 2012, the mill has been greatly improved and enhanced. Fineness of which processing has reached 3,000 projects, Henan Hongxing mechanical engineer to tell you, in the production process should not underestimate the mill spills and other minor problems, identify problems and timely solutions is a good way to improve productivity.

Working with cement vertical mill difficulty to be solved
Grinding procedure and issues of ball and roller mill grinding approach is distinctive. Material in a ball mill is crushed by the influence and friction; and the material in the vertical grinding mill suffered extrusion force is based, supplemented by grinding; shorter grinding materials inside the vertical mill, 2-3 min to complete, and hence
Higher grinding efficiency, saving grinding energy consumption. Normally vertical roller mill can grind the opposition than milling, inside the raw material or pulverized coal grinding mill within the raw water is higher, generally up to 5 or far more, for drying capacity needs are reasonably higher, whilst the cement grinding mill material into dry , no moisture or low drying capacity requirement is secondary
; The raw material grinding fineness much less demanding, the common control of 0.08 mm sieve 12 is usually, for straightforward burning with superior raw material for the fineness of precalciner can even be relaxed to 15 to 20, but additionally for particle size distribution base will not be necessary, but persons around the cement item fineness and particle size distribution are greater, and cement fineness
Common needs Blaine specific surface area of ??more than m / kg.
By vertical roller mill grinding cement, the main challenge to become solved could be the mill vibration, severe wear and disc grinding roller as well as the cement quality.
Due to dry materials, goods and cement grinding fineness needs, material circulation volume, circulation material is quite fine, excellent liquidity, operating under the influence of centrifugal disc, and soon left towards the disc outer rings blown by the wind speed airflow away, it really is tough to form a steady material layer. Moreover, since the abrasive cement clinker
Relatively strong around the disc plus the roller will produce a lot more significant wear and tear, causing mill production decline and increased operating expenses and also other concerns in addition when it comes to solution good quality, mill produces a wide range of cement particle composition, he incurs the over-grinding The fine particles are a lot more, but an additional element just isn't sufficiently coarse grinding
Particles, and inside the RRB size distribution curve slope worth smaller than the diameter on the regular distribution curve is flat, spherical particles tend to form comparison. And much less material inside the classic vertical mill residence time, grinding track is shorter, so the vertical roller mill cement particles is narrow, the bigger its RRB worth curve, and much more commonly
Above 1.ten, whilst cement milling is usually 0.95 to 1.05. Fine particles as well smaller may perhaps bring about low early strength, but the primary causes enhanced water demand.
