MTM Medium Speed Trapezium Mill
MTM Medium Speed Trapezium mill is widely used in many industrial fields, such as building, chemical fertilizer, chemical, metallurgy, nonmetal, mining, abrasive, bearing materials, steel, ceramic, thermal power, bricks & tiles, coal industry, etc. It can grind these materials which are 9 or less on the Meshes scale, and moisture is below 6%, and they should be non-explosive and non-flammable 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, calcite, gypsum, feldspar, limestone, dolomite, graphite, fluorite, aedelforsite, phosphate ore, fused calcium-magnesium phosphate, car amide, granite, orthoclase, marble, electrolytic manganese metal, ferromanganese, coal, gangue, slag, zirconium, steatite, barites, ceramics, glass, etc.
five technical advantages:
1、The ladder-shaped rollers and rings improve crushing efficiency greatly. The rollers and ring are designed in the main machine of an inverted trapezium, which control the material’s slip velocity between rollers and rings. They can extend the grinding time, and enhance the crushing effect.
2、The press springs with balancing and pressurized function and the forming resilient connection with steady and vibration reducing function are invented into our machines. The symmetrical roller assembly is connected by horizontally-placed spring rod. When the large materials impact one roller assembly, to keep balance, the radial force will pass to another roller assembly, which is on the plane of symmetry through spring rod. Under this condition, the whole device’s bearing is improved to be 40% on the other mills; and the forming resilient connection can reduce the vibration and noise, also it can avoid resonance.
3、The powder classifier adopts high density impeller, which can increase precision of powder and capacity. It has been proved that: under fixed spindle speed, to 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, our machine can reduce resistance of air’s flow, the capacity can be improved more than 50% over the traditional one.
4、There is high-efficiency and energy-saving blower installed on our machine. 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%.
5、There is convenient impeller adjusting device. The clearance between housing and ending of powder classifier’s blade also effects fineness. Our mill is convenient to adjust the fineness.
