Detailed Product Description
Product Name: MTM Medium Speed Trapezium Mill
Model Number: MTM
Place of Origin: China

MTM medium speed trapezium mill is a leading world level industrial mill. It is designed by our engineers and technical workers, based on many years'' industrial mill design, adopting world leading powder making technology. Our machine adopts numbers of national patents of mill, such as trapezium working surface, flexible connection, roll linked pressure boost. It has totally overcome many defects of traditional mills in application, capacity, fineness, energy consumption, and service life, and it is the ideal substitute of traditional mill, such as Raymond mill, high pressure suspension mill, and ball mill. Nowadays, it has widely used in metallurgy industry, electric power industrial, chemical, building, steel industry, and coal industry and it has achieved large economic benefits and social benefits.

It is mainly used in such areas as building, chemical, chemical fertilizer, metallurgy, mining, nonmetal, abrasive, bearing material, ceramic, steel, thermal power, bricks and tiles, and coal industry. It can grind these materials whose Moth''s hardness is below 9.3 grades, and moisture is below 6%, and they should be non-explosive and non-flammable mining materials. The final size can be adjusted between 30 to 400 meshes according to your requirements. There are thousands of materials our machine can grind, and here are some of them and they are just for you reference. They are cement (raw meal and cement clinker), quartz, feldspar, calcite, gypsum, limestone, dolomite, graphite, fluorite, aedelforsite, and ferromanganese.

It has such characteristics as new design, reasonable structure, smaller size, lower energy consumption, longer service life and lower cost of easy worn parts, and higher performance cost ratio. All its technical performance has reached leading international level. Compared with Raymond mill, ball mill, and high pressure suspension mill, it has these five technical advantages:
1) The ladder-shaped rollers and ring improve crushing efficiency greatly. The rollers and ring are designed in inverted trapezium, which reduce the material''s slip velocity between rollers and ring, extend grinding time, and enhance crushing efficiency
2) The press spring with balancing pressurized function and the forming resilient connection with steady and vibration reducing function. Our machine adopts level principle. The symmetrical roller assembly is connected by horizontally placed spring rod. When the large material touches the roller assembly, to keep balance, the radial force may pass to the roller assembly which is plane of symmetry through spring rod. Under this condition, the whole device''s bearing is improved about 40% than that of others； the forming resilient connection can reduce the vibration and noise, and avoid resonance
3) The powder concentrator impeller enhances powder precision and high density product. It is proved a fact: under uniform spindle speed, enhancing the density of impeller is to enhance the fineness of final products. In other words, when it is unnecessary to alter the fineness of final product, the spindle speed of high density impeller is lower than the low density one, thus reduce resistance to air flow and its capacity is improved more than 50%, under the same power
4) There is high-efficiency and energy-saving centrifugal induced draft fan. The efficiency of prismatic blade equipped on the traditional machine is only 62%, but the efficiency of the energy saving induced draft fan whose impeller and blade are both stamping is 85%
5) There is convenient impeller adjusting device. The clearance between housing and end of powder concentrator''s blade also effects fineness. This patent technology is convenient to adjust the clearance
