Qualified powders mill

applies to grind coal, coke, cement raw material, gypsum, barite, phosphorite, calcite, kaolin and other medium degree hardness solid material. The system enters raw materials warehouse by bucket elevator , after weighing, in addition to the iron belt conveyor into the air lock feeder , as much as possible to ensure that when the raw material into the mill no strings wind. Products with a pulse dust collection to complete , reducing the number of units of equipment, simplifying the configuration of the system. is characterized by high efficiency, rolls , The grinded materials will be taken up by air circulation and the bigger powders will fall down for regrinding. Qualified powders will be collected by collecting device as to be final product. Materials containing water will be dried when they contact with the hot air. Different humidity materials can be dried to the requirement through adjusting the temperature of hot air. Adjusting the separator can get the required fineness powders. Vertical Roller Mill's motor runs under the condition that speed reducer drives the Nether millstone. The materials fall into the center of device through lock air feeder, and hot air comes into mill through air inlet. Under the function of centrifugal force, the materials move to the edge of the Nether millstone as it runs and rollers will grind the materials when they come by the annular chute.
