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.
