Natural Classification Research of the Mill

 Due to  the media characteristics of the motion and the phenomenon of  the natural classification exists in the ball mill , Vertical screw mixing mill has a high grinding efficiency, energy consumption provinces and low noise these characteristics , it is a  finely ground equipment have broad development prospects . This series ball mill is Tsinghua University's  patented product, it consist of an electric motor, reducer, shaft, mixing tube, and electrical control systems, rack six part .  its work principle is : through the pump system from the simplified catchy , slurry were put into  a certain amount of grinding media  barrel, stirring axis were driven by the motor, and through the stirring rod's strong mixing and dispersion, so that the slurry and grinding media were received the generated strong pressure or impact, grinding, cutting, so as to achieve high fine grinding results. The pulverized finished slurry  outflow through the lower part of the nesting f_1 filter.
The technical characteristics of the device:(1) this machine  absorb the characteristics of the home and abroad stirring grinding, sanding and other equipment, it is equipped with high efficiency, large capacity, easy operation and  easy maintenance  these advantages.according to the  stirring rod form ,it can be divided into A and B are two types; ② medium size ratio of particle size is made based on the types of materials, raw materials and products using optimization designed so as to maximize its grinding capacity, and material separation; ③ the cylinder and stirring rod use the efficient shaped structure, according to users' needs ,they can be made into polyurethane rubber or inorganic resistant lining, and without iron contamination; ④  system made of the mud pump can form a self-loop continuous operations; ⑤ equipped with external cooling system, to ensure that the grinding temperature is kept at a lower state; ⑥ adopt horizontal reducer, without oil leaking. Start the coupler, and the starting is smooth,  the torque is big. It can be used widely in wet ultrafine grinding of zircon sand, silicon carbide, TSP, and other non-metallic minerals and building materials, chemical raw materials.
 
The application of heavy calcium carbonate ultra-fine grinding: Superfine heavy calcium carbonate is mainly used in industries such as rubber, plastic, paper, ink and paint. High value-added superfine heavy calcium carbonate need to have the following requirements: chemical purity of CaCO ≥ 98%,  the whiteness is'90% , fineness -2 um ≥ 90%.  After the improvement of the vertical auger mixing mill . Lined with polyurethane, blender polyurethane production, the external use the  pump cycle operation. Changning heavy calcium carbonate company in 1996 ordered a φ800 mm vertical screw mixing  ball mill, produced-2um ≥ 90c / o of superfine heavy calcium carbonate products. The process is characterized by simple technology, low investment, ideal for township enterprises and small and medium-sized enterprises. Vertical screw mixing mill bauxite, blast furnace slag, fly ash, garnet, mica, wollastonite, illite, K Stone, aluminum powder, paste, ferrite magnetic materials, iron oxide, industrial minerals such as cadmium red test, the effects are good.
