Grid Liners. All ball mill liners must be very resistant and capable of withstanding high impacts. The milling process uses steel balls to break down the material. The grid liner has the dual role of protecting the cylinder while making the movement of the steel balls effective. Double Wave Liners. People also use double wave liners for ball mills.

Uses of a Ball Mill Liner. The role of a ball mill liner is to give the mill heads protection against wear and tear thus increasing their lifetime and creating optimal grinding efficiency. The design of a ball mill liner depends on the drilling pattern of the mill heads, the rpm speed of the mill, the maximum grinding diameter of the media and the percentage of media filling.
