R-type Raymond mill after many years of practice and continuous improvement 3r2615 Raymond, whose structure has been increasingly sophisticated, highly efficient, low power consumption, small footprint, low capital investment and environmental pollution. Which is widely used in the grinding process metallurgy, building materials, chemicals, mining minerals in areas such as materials, suitable for processing Mohs hardness below seven, various non-explosive mineral humidity below 6%, such as gypsum, talc , calcite, limestone, marble, feldspar, barite, dolomite, granite, kaolin, bentonite, stone, bauxite, iron oxide red, iron ore, finished fineness 613 microns to 440 microns ( 0.613 mm -0.44 mm) between 3016 Raymond, interaction analysis by machine and fans can meet the different requirements of users. After much discussion and research Raymond 6r, we Raymond machine grinding rolls heat treatment of the material itself. After heat treatment of the roller on the solution to the problem of high hardness easy to break. But there is a problem now, is that we increase the hardness of the time, the composition of the material is applied to the material change. After Raymond composition changes, the higher the hardness of the casting, but this time a problem arises, the lower its toughness, easy to break.
