Grid Ball Mill

The grid ball millis used to grind various of ores and other materials,and it is widely ysed in mineral processing, construction and chemical industry and other economic sectors. Grid ball mill's structural features: Grid ball mill is composed of feeding part, discharging part, rotation part and driving part (reducer, small driving gear, electric motor and electric control)and other major parts.The hollow shaft uses steel casting, the lining can be replaced, rotary gearwheel made with casting gear hobbing for process, the cylinder body beset with wear-resisting backing board, has good wear resistance. The operation of this ball mill is very stable and reliable. Grid ball mill's advantages: The discharging port's pulp surface is low,the pulp can pass quickly to reduce ore excessive wear; put more balls,big balls and small balls can be loaded,and small balls can't be discharged,but also form a good working conditions;under the same sondition,production capacity is higher, power consumption is low,its disadvantage is complex structure.But overflow-type ball mill has simple structure,management and maintenance are more convenient,so the operating rate is relatively high.Generally,fine grinding fineness is suitable for overflow type,thick grinding fineness is suitable for grid type(to avoid excessive wear to have negative effects).
