Application:

Our MTM Medium Speed Trapezium Mill adopts numbers of national patents, such as trapezium working surface, flexible connection, roll linked pressure boost, etc. It has completely overcome traditional mill’s defect in application fields, capacity, fineness, energy consumption, service life, etc. it has been widely used in metallurgy industry, electric power industry, chemical, building, steel industry, coal industry, etc. And it has achieved large economic benefits and social benefits.

Features and benefits:

1. The ladder-shaped rollers and rings improve crushing efficiency greatly. 
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. 
5. There is convenient impeller adjusting device.

Working Principle:

The main unit runs with 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 swing support, the grinding roller not only rotates around its own axis, it also rotates around the grinding ring and rotates itself due to the friction. There is spade system under the quincunx stand, which is at eh 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.
