MTM Medium Speed Trapezium grinder is a leading-world-level industrial mill. It is designed by our own engineers and technical workers, basing on industrial mill research of many years and adopting world-leading-powder processing technology. Our machine adopts many advantages from numbers of mill all over the world, such as trapezium’s working surface, flexible connection, roll linked pressure boost, etc. It has overcome the traditional mill’s defect completely in application, capacity, fineness, energy consumption, service life, etc. And it is the ideal substitute of the traditional mill, such as Raymond mill, high pressure suspension mill, ball mill, etc. Nowadays, our products have been widely used in metallurgy industry, electric power industrial, chemical, building, steel industry, coal industry, etc. And it has brought large economic benefits to our customers and the society.

Technical advantages

position. Compared with the traditional one ,MTM Medium Speed Trapezium Mill has five advantages as follows:
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 controlling the material’s slip velocity between rollers and rings,which 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. To keep balance, the radial force will pass to another roller assembly, which is on the plane of symmetry through spring rod when the large materials impact one roller assembly. Under this condition, the whole device’s bearing is improved by one half compared with the other mills; and the forming resilient connection can reduce the vibration and noise, and it can also avoid the resonance.
3、The powder classifier adopts high density impeller, which can increase precision of powder and capacity. It has proved that: under the 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 by more than 50% over the traditional one.
4、There is a 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 is 85% , whose impeller and blade are both stamping,.
5、There is a convenient impeller adjusting device. The clearance between housing and ending of powder classifier’s blade also effects the fineness. Our mill is convenient to adjust the fineness.
