According to different grinding requirements, ball mill liners are roughly divided into 9 types, which are wedge-shaped, corrugated, flat-convex, flat, stepped, elongated, rudder-shaped, K-shaped ball mill rubber liner and B-shaped ball mill rubber liner. These 9 kinds of grinding mill liners can be classified into two categories: smooth grinding mill liner and unsmooth grinding mill liner.

Secondary Grinding Ball Mills experience 1-2 years of liner life, depending on tonnage/ball size. Normally Lifter to Plate ratio is 1:2.Tertiary Grinding Ball Mills experience up to 4 years of liner life. Since, all the mills are unique in their operation and the practical sense in which they run, we do wear measurement during every shutdown.
