Our machine adopts many patents of mills, such as trapezium working surface, flexible
connection, and roll linked pressure boost. It has completely overcome traditional
mill's defect in application, capacity, fineness, energy consumption andservice life. It is widely used in building, chemical, chemical fertilizer, metallurgy, mining, nonmetal, abrasive, bearing Materials(China Stone), ceramic, steel, thermal power, brick, tile, and coal industries. It can grind all the Materials(China Stone) which are 9 or less on theMohs scale with moisture below 6%, and non-explosive and nonflammable miningMaterials(China Stone). The final size can be adjusted from 30 to 400 meshes easily.

      There are thousands of Materials(China Stone) our machine can grind. The typical Materials(China Stone) are cement(raw meal and cement clinker), quartz, feldspar, calcite, gypsum, limeStone(Imperial Brown), dolomite,
graphite, fluorite, aedelforsite, phosphate ore, fused calcium magnesiumphosphate, carbamide, electrolytic manganese metal, ferromanganese, coal, gangue,
slag, zirconium, steatite, Granite(Kashmir White), orthoclase, Marble(Kashmir White), barytes, ceramics, andglass.This mill has many technical advantages.Firstly, the ladder-shaped rollers and ring improve crushing efficiency greatly.
      The rollers and ring are designed in inverted trapezium, which reduce the material's
slip velocity between rollers and ring, extend grinding time, and enhance crushing
effect.Secondly, the press spring with balancing pressurized function and the forming resilient
connection with steady and vibration reducing function: Our machine adoptslevel principle. The symmetrical roller assembly is connected by horizontallyplaced spring rod. When the large material impact one roller assembly, the radial
force may pass to another roller assembly which is on the plane of symmetry through
spring rod to keep balance. Under this condition, the whole device's bearing is
improved about 40% than others. The forming resilient connection can reduce the
vibration and noise, and avoid resonance. Thirdly, the powder classifier adopts high density impeller which can increase powder
precision and capacity. It is a proved fact that under fixed spindle speed,enhance the density of impeller is to enhance the fineness of final products. In
other words, when the fineness of final product is fixed, the spindle speed ofhigh density impeller is lower than the low density one, thus under the same power, the density one reduces resistance to air flow, the capacity is improved morethan 50%.Fourthly, there is high-efficiency and energy-saving blower. The efficiency of prismatic
blade equipped on the traditional machine is only 62%, but the efficiencyof the energy saving blower whose impeller and blade are both stamping is 85%.Lastly, there is convenient impeller adjusting device. The clearance between housing and end of powder classifier's blade also effects fineness. Our mill is convenient
to adjust the clearance.
