Beneficiation mill performance characteristics 
 I produced the beneficiation mill is composed of the main part of the feeding part, discharging part, turning part, transmission part (reducer, small driving gear, motors, electrical control) and so on. The hollow shaft using steel, lined with removable rotary gear casting hobbing process, the body inlaid cylinder liner wear, has good wear resistance. The operation of the machine is stable, reliable work. 
 Beneficiation mill works 
 Beneficiation mill is simplified by the level expected out of the hollow shaft and the grinding head parts, simplified for a long cylinder, cylinder equipped with a grinding body, tube steel plate, steel liner and Simplified fixed grinding media in general steel ball, according to different diameter and a certain percentage into the tube, the grinding media can also be used to the steel segment, to be selected according to the granularity of the abrasive material, material mill feed-side hollow shaft load of the cylinder body, when the dressing mill Simplified rotation when grinding media due to inertia and centrifugal force, the role of friction, so that it posts near the cylinder liner, cylinder away and was taken to a certain height, when, being thrown by its own gravity like projectile, the whereabouts of the grinding media, like the cylinder body of material to crushing. 
 By material from the feed device into the compound by the air shaft spiral evenly into the mill's first warehouse, the warehouse there are ladder liner or corrugated liner, built-in different specifications of steel balls, dressing mill rotating cylinder produces centrifugal force to the ball a certain height down pounding and abrasive materials. The material in the first position, the coarse grinding, the single-layer diaphragm plate into the second position, the warehouse lined with flat lining, steel ball, the material further grinding. Powder through the discharge grate plate to complete the grinding operation. 

 Roller Ball Mill in the rotation process, the grinding media have slipped to the abrasive to the material in the slip process, in order to make effective use of the abrasive particle size to teach the general 26-mesh pulverized when the mill body tube with separated compartment plate, Sec, become two positions, the material into the first position when the ball crushed, the material into the second position when the steel side of the material grinding, Ground qualified materials from the hollow shaft of the feed-side discharge, finely ground when the feed particles of material 2, such as sand and slag, coarse fly ash beneficiation mill shell from time to set up partitions to become a single-chamber tube mill grinding volume can also be the steel segment.
