MTM Medium Speed Trapezium Mill is a leading-world-level industrial mill.The Mill 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 trapeziums working surface, flexible connection, roll linked pressure boost, etc.The Mill has overcome the traditional mills 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.

Operation principle of main unit Of The Grinding Mills:

Main unit runs with the central shaft that is driven by a decelerator. The top of the shaft is connected with a quincunx stand, on which a grinding roller is installed to form a swing support. The grinding roller not only rotates around the central axle and grinding roller, but also rotates around its own axle due to the friction. There is pallet knife system at bottom of quincunx stand. The pallet knife system is under the grinding roller. With co-rotation of pallet knife and grinding roller, pallet knife will lift the materials into the space between roller and ring to form a material layer. The materials will grinded due to centrifugal force of roller.
The classifier drives the impellers on the tray to rotate through speed adjusting motor, so that powder can be separated. The standard particles will enter cyclone collector. After being separated from the air flow, powder will be collected. Substandard particles will be thrown to the outside wall, to be separated from the air flow. Heavy powder will fall into the grinding chamber to regrind due to self gravity.

Technical Advantage Of The Grinding Mills:

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.
3、The powder classifier adopts high density impeller, which can increase precision of powder and capacity.
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.
