Batch Ball Mills Plant

Either wet grinding or dry grinding may be conducted in the batch ball and rod mills. Usually, wet grinding is more efficient than dry grinding, however in laboratory operations, adding liquid is not feasible. The jars should be charged with at least 20 pounds of balls, and 25%to 40%, by volume,material to be ground.The finished product then may fall into a drawer or bin in the lower part of the housing for immediate removal. Sometimes it is dropped into a storage hopper for bagging, while the next batch is grinding in the Mill above. Other times it may fall from the housing into a dust-proof chute to the floor below.

The batch ball and rodmill consists of the grinding cylinder with four lifter bars,machined rolling rings, threaded removable yoke, hand lever for tightening and loosening the lid, amachined lid with neoprene gasket. Materials of construction are mild steel, 316 stainless steel or mild steel lined with urethane.To discharge dry products, the grinding cover is removed and exchanged for a slotted cover. Then, after the housing is shut tightly, the Mill is revolved until all the fine grindings sift through the grate into the dust-proof housing while the grinding media are retained in the Mill by the slotted cover.

The vent plug in the head of the Mill has two primary functions. The first is to aid in the loading and discharging of the Mill. During loading the use of a vent alleviates surging of the liquids in the batch. During unloading, the vent plug should be removed before the cover or discharge valve is opened. The vent permits more rapid discharging than would be possible if the vacuum created by the discharging action were not destroyed by air rushing in through the vent. The Copper Ore cascading effect reduces the material to a fine powder. Industrial ball mills can operate continuously, fed at one end and discharged at the other end. Large to medium-sized ball mills are mechanically rotated on their axis, but small ones normally consist of a cylindrical capped container that sits on two drive shafts.
