Dry ball mill is the material to be broken, and then grinding the key equipment, which is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, ferrous and nonferrous metal and glass ceramics and other production industries all kinds of ores and other grind-able materials can be dry grinding. Dry ball mill structure: 1, the feed screw, so that a uniform feed for feed use. 2, the barrel portion, someone opened a dry hole Ball Mill, in time for repair and replacement of cylinder liners available. 3, the discharge portion for discharging qualified products mill with four main bearing parts. 5, transmission parts. Note: According to the process needs dry ball mill, mill points left and right hand, press delivery order contract delivery. Structural features dry mill: dry ball mill by feeding part, discharging part, turning part and driving part (reducer, small transmission gear, motors, electrical control) and other major components, hollow shaft with steel parts, within lining removable, rotary gear hobbing using casting, body inlaid cylinder liner wear, has good wear resistance, this machine running smoothly, reliable, low hardness of the material used for grinding, and the other: according to the material and methods of discharge, optional dry ball mill and dry lattice-type ball mill. Dry ball mill works: dry ball mill is a horizontal cylindrical rotating device, outer gear, the two positions, lattice-type ball mill, the material from the feed device into the compound by the air shaft into the mill screw evenly the first warehouse, the warehouse has ladder liner or corrugated liner, built with different specifications steel ball, rotating cylinder produces centrifugal force to the ball a certain height After the fall, have severe impact on the material and abrasive material in the first warehouse, coarse After, the single-compartment plate into the second warehouse, the warehouse lined with flat lining, the steel ball, the material further grinding, powder discharged through the discharge grate plate to complete the grinding operation.
