Based on the adoption of the world-class technology of the mill and years' research ,our company has developed this industrial grinding mill with the world advanced level.MTM Medium Speed Trapezium Mill adopts many national latest grinding proprietary technologys ,such as ladder-shaped working surface , flexible connection, roll linked pressure boost, etc. It has totally over many defects of traditional mill, like application, capacity, fineness, energy consumption, service life, etc and it is the ideal substitute of traditional mill, such as Raymond mill, high pressure suspension mill, ball mill, etc.And it has created enormous economic and social benefits .Nowadays, our products have been widely used in metallurgy industry, electric power industrial, chemical, building, steel industry, coal industry, etc.
Working Principle :
The main unit runs with the a central shaft driven by a transmission device .The top of the shaft is connected with a quincunx stand,on which a grinding roller is installed to form a awing support ,the grinding roller not only rotates around its own axis ,but also rotates around the grinding ring and rotates itself due to the friction. There is spade system under the quincunx stand ,which is at the bottom end of the grinding roller .During rotation of the spade and the rollers ,materials will be fed into the space between rollers and ring to form a material layer.The materials will be grinded due to centrifugal force.
Technical advantages:
With many national latest grinding proprietary technologys ,it features the unique design ,reasonable structure ,long service life ,low cost of the wearble parts ,and the high performance,etc.And its every performance have reached the world class 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.
6. Unique design of the air duct with the leaning inward ensures that the materials which have entered the wind scoop shell can smoothly fall in the grinding mill along the slope.
