The Raymond mill（MTM Medium Speed Trapezium Mill） is a leading world level industrial mill.The mill machine is designed by our engineers and technical workers, basing on many years’ industrial mill research, and adopting world leading powder processing technology. Our mill machine adopts numbers of national patent of mill, such as trapezium working surface, flexible connection, roll linked pressure boost, etc. The Raymond grinder machine has completely overcome traditional mill’s defect in application, capacity, fineness, energy consumption, service life, etc. And it is the ideal substitute of traditional mill, such as Raymond mill, high pressure suspension mill, ball mill, etc. Nowadays, the mill machine has widely used in metallurgy industry, electric power industrial, chemical, building, steel industry, coal industry, etc. And it has achieved large economic benefits and social benefits. Application The Raymond grinder is widely used in many industrial, such as building, chemical, chemical fertilizer, metallurgy, mining, nonmetal, abrasive, bearing materials, ceramic, steel, thermal power, bricks & tiles, coal industry, etc. The mill machine can grind these materials which are 9 or less on the Mohs scale, and moisture is below 6%., and they should be nonexplosive and nonflamable mining materials. The final size can be adjusted from 30 to 400 meshes easily. There are thousands materials our machine can grind. The typical materials are cement (raw meal and cement clinker), quartz, feldspar, calcite, gypsum, limestone, dolomite, graphite, fluorite, aedelforsite, phosphate ore, fused calciummagnesium phosphate, carbamide, electrolytic manganese metal, ferromanganese, coal, gangue, slag, zirconium, steatite, granite, orthoclase, marble, barytes, ceramic.
