MTM Medium-speed Grinding Mill is an industrial mill developed by our company based on years of research and development of industrial mills. It introduces industrial milling technology, and organizes technical experts and related engineers to design, test and improve it. This machine adopts a number of patented grinding machine technologies such as trapezoidal working surface, flexible connection, and grinding roller linkage pressurization. . At present, this model has been widely used in metallurgy, electric power, chemical industry, steel, building materials, coal and other industries, which has produced economic benefits.

MTM trapezium grinder can be called as the MTM trapezium grinding mill. It is the popular grinding equipment for mining and construction industry. SBM can guarantee the high quality and high yield in the production line for over 20 years' abundant production experience and advanced technology. It also can be used in coal industry to break rock materials for sale.


Working Principle:

Big block material after broken jaw crusher to required size, the elevator will material sent to the storage hopper, then through vibrating feeder will feed the uniform quantitative continuously into the indoor host grinding of grinding, grinding after SBM with fan air currents to rise, the classifier for classification, fineness SBM varies with air flow through pipe into the big cyclone collector, separation and collection by the powder discharge valve is the finished product SBM. Airflow by large whirlwind powder top return air duct suction centrifugal induced draft fan, the machine the entire air system is a closed loop, and is under negative pressure condition of circulating.


MTM trapezium grinder is designed for the needs of the desulfurization system of powder and it can be perfect matched with sweetener to enhance the efficiency. It becomes the first choice for the sulfur powder at home and abroad. Now the machine has been widely used in electric power, mining, metallurgy, chemical industry, building materials, coal, refractories and other industries, has a huge economic and social benefits.

  • The crush pressure is greater

    The trapezoidal mill absorbs the advantages of the ramon mill and the overhanging roller mill, and connects the grinding roller assembly to each other through the pull rod and the horizontal spring. The radial force generated by the grinding roller avoids the loss of the large material to the spindle and bearing. At the same time, under the joint action of the high pressure spring and the centrifugal force, the material is fully squeezed, thus increasing the output.

  • High precision of finished products

    Under the condition of constant rotation speed, the fineness of finished product can be improved by increasing the density of blade. In other words, under the condition that fineness of finished product does not need to be changed, high density impeller is lower than low density impeller. By reducing airflow resistance, the output of finished products under the same power can be increased by more than 50%.

  • High level of environmental protection

    The main engine and the powder separator adopt soft connection, the shock absorption spring and the sealing belt can reduce the vibration and noise, and also avoid the resonance. High efficiency dust removal equipment, rigorous parts processing technology, to ensure that the dust pollution to lower, to meet the national standards.

  • Better stability

    The main engine, powder separator and fan adopt soft connection, which can reduce the vibration and noise, avoid the damage caused by resonance to the equipment, and also avoid the impact on the quality of finished products. A large inclined air duct is adopted to ensure that the wind entering the volute can blow smoothly into the main grinding chamber along the inclined surface.

  • Easier to operate

    The size of clearance between the blade end and the shell of the powder separator can be adjusted conveniently and quickly by adopting convenient impeller adjustment device. Equipment operation is simple, one person can easily operate.
