Overflow Ball Mill


overflow ball mill

【Introduction】

Overflow ball mill has simple structure, Relying on the discharge end of the hollow shaft diameter is slightly larger than the feed end of the hollow shaft, causing the inner pulp mill for the discharge end of a certain inclination to discharge mine. When the pulp surface height is higher than the minimum inner diameter of the discharge port bus, then overflow discharge pulp mill. This non-forced high material level of discharge, grinding adequate, good grinding effect. Generally applies to fine grinding in the one stage or two stages grinding.


【Production Capacity】

0.17~170t/h



【Work Principle】

Materials are put in cylinder through the feed opening and then thoroughly grinded. The falling course of iron balls and ores can produce huge falling impact and autogenous grinding. The continuous feeding of ores can create considerable pressure to make ores move from feed opening toward discharge opening. Finally, acceptable particles are discharged from the discharge opening. Hollow shaft with the anti-spiral blade returns the steel ball and the coarse ore block.Wet type overflow ball mill works for fine fineness grinding.

The main component of overflow ball mill is a cylinder with bigger diameter and smaller length which is revolved by transmitting machinery.

【Advantages】
overflow ball mill principle1.  Overflow ball mill is lined with Xinhai wear-resistant rubber sheet with excellent wear resistance, long service life and convenient maintenance.

2. The oil-mist lubrication device guarantees reliable performance of bearings.

3.The gas clutch adopts the flexible start-up model.

4.  Low speed transmission is easy for starting and maintenance.
