Hi-pressure suspension grinder(High Pressure Mill) is a new type product, which is developed on the basis of Raymond grinder. Compared with the Raymond grinder, under the function of strongpressure spring, the pressure between roller and materials can be improved by 1500KgF; the output can be improved by 10% under the same powder condition. The machine are widely used in grinding more than 320 noninflammable and nonexplosive materials with a Moth's hardness below 9.4 scale, a humidity below 6%, such as barite, calcite, limestone, potash, ceramic, slag, glass, manganese, chrome and other materials used in mining, construction, chemical and metallurgy. The sizes of powder can be controlled ranging from 80 to 480 meshes, minimum size can reach 1000 meshes. By being equipped particular parts, the High pressure mill can produce thick powders ranging from 30 to 80 meshes and output will be higher.
