Medium Speed Trapezium Mill is widely used in building, chemical, chemical fertilizer, metallurgy, mining, nonmetal, abrasive, bearing materials, ceramic, steel, thermal power, brick, tile, and coal industries. This mill can grind all the materials which are 9 or less on the Mohs scale with moisture below 6%, and non-explosive and nonflammable mining materials. The final size can be adjusted from 30 to 400 meshes easily.

There are thousands of materials our machine can grind. The typical materials are cement (raw meal and cement clinker), quartz, feldspar, calcite, gypsum, limestone, dolomite, graphite, fluorite, aedelforsite, phosphate ore, fused calcium magnesium phosphate, carbamide, electrolytic manganese metal, ferromanganese, coal, gangue, slag, zirconium, steatite, granite, orthoclase, marble, barytes, ceramics, and glass.

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 adopts level principle. The symmetrical roller assembly is connected by horizontally placed 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 of high 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 more than 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 efficiency of 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.
