Grinding Mills and Their Types IspatGuru

Apr 09, 2015 The mill is normally used for grinding of ores. Lining of the cylinder plays very important role. It protects the mill from abrasions and at the same time it helps in lifting of the material from the bottom of cylinder. The types of lining are (i) smooth liner, (ii) wave liner, (iii) ship lap liner, (iv) step liner, and (v) Osborn liner.

Grinding Mills an overview ScienceDirect Topics

The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many low-grade, high-tonnage operations such as copper and gold ores feasible. Future circuits may see increasing use of high pressure grinding rolls (Rosas et al., 2012).
