SINGLE / MULTIPLE COMPARTMENTS CYLINDRICAL BALL MILL

Listing ID #4256853

Single compartment Mill is a conventional type of batch mill, consists of cylindrical steel shell with flat steel ends welded to shell. Ball Mill rotates around a horizontal axis partially filled with raw materials to be ground plus the grinding medium. The material and the grinding medium are fed and discharged through an opening manhole on the cylinder shell. Ball Mills usually have replaceable liners inside and replaced when they wear out. Material fed through the mill is crushed by impact and grounded through attrition between the balls.
Design Features
The horizontal cylinder of the ball mill, which is fabricated out of mild steel plates, is rotated using a side drive system at one end of the mill. The drive comprises of a girth gear, generally made from alloy steel casting, bolted onto the mill which is driven by its pinion, generally made out of alloy steel forging, through a gear reducer and motor coupled together.
The two ends of the cylinder are covered with mill headers one placed at each end, the inlet and at the discharge. The mill headers have a central inlet and discharge opening from where the material enters the mill and exits the mill. These mill headers are generally made out of alloy steel casting. The mill headers are rested on fabricated trunions at both ends on which the headers rotate on a special self lubricating white metal lining. External lubrication system is also provided to keep the mill headers properly lubricated at all times. Other accessories include a set of low pressure and high pressure pumps which help to pre-jack the mill during startup.
