SBM MTM trapezium grinding mill is the ideal substitute of the traditional grinding mill, such as Raymond mill, high pressure suspension mill, ball mill, etc.
MTM grinding mill widely used in metallurgy industry, electric power industrial, chemical fertilizer, building, steel industry, coal industry, mining and construction, nonmetal, abrasive, bearing materials, ceramic, thermal power, bricks & tiles, etc. And it has brought large economic benefits to our customers and the society.
MTM grinding mill is widely used to 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. ,such as cement (raw meal and cement clinker), quartz, feldspar, calcite, gypsum, limestone, dolomite, graphite, fluorite, aedelforsite, phosphate ore, fused calcium-magnesium phosphate, car amide, electrolytic manganese metal, ferromanganese, coal, gangue, slag, zirconium, steatite, granite, orthoclase, marble, barites, ceramics, glass, etc.

In the grinding mill, air is driven into the undersurface of the grinding ring and flows upward, carrying fines to the classifying section. The classifier allowed the pulverized material to pass and the oversized particles are drove back to the grinding chamber for further processing. The whole mill operates under negative pressure conditions, which can maximize the service life of major mechanical components. Thus minimizing mill maintenance and plant housekeeping problems have been solved.
SBM MTM Medium Speed Trapezium Mill is new grinding mill designed by our experts with great concentration on the basis of experience of long term study. This grinding mill adopts the five patent techniques such as trapezium working surface, flexible connection, and interlocked grinding roller turbo etc. It has overcome the traditional mills defect completely in application, capacity, fineness, energy consumption, service life, etc.
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.
