Profile: Shanghai JingXiang Heavy Machinery Co., Ltd. offers environmental industrial milling machines and heavy crushing & screening equipment. The machinery is widely used in metallurgical, chemical, building materials, coal, ceramics, roads, railways, tunnels bridges, airport constructions, hydro-power projects, refractories, and other industries. Vertical grinding machine adopts a working principle in which the motor drives the grinding table through the decelerator. The materials fall down the center of grinding table from feed opening. At the same time, hot air comes into the mill from the air inlet. Due to the centrifugal force, materials move to the edge of the grinding table. The materials are pulverized by the roller when they pass by the groove on the grinding table. The crushed materials are brought up by the vane high-speed air stream, and the larger particles fall down to the grinding table for re-grinding. When the materials in the air stream pass the separator on the top of the mill, the coarse powder falls down the grinding table for re-grinding under the function of the rotation rotor. The fine powder comes out with the air stream, and is gathered by the dust catcher. The material content with moisture will be dried when they meet the hot air stream. Through adjusting the temperature of the hot air stream, it can meet different materials requirement, and also through adjusting separator, it can reach proper fineness of materials.
