WhatsApp: +86 18838072829Uses 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.
WhatsApp: +86 18838072829Ball mill energy consumption can be improved by changing its rotational speed when grinding efficiency decreases or by modifying the mill liner shape in a way that ball trajectory can be maintained within an optimum range for the longest period of time possible.
WhatsApp: +86 18838072829Ball grinding can be carried out in either dryoperation or wetoperation. The former is widely used in coalfired power plants and cement industry, and the latter is widely used in metal and nonmetal mines. There are three types of mills used: grate ball mill, overflow ball mill, and peripheral discharge ball mill.

WhatsApp: +86 18838072829The most common types of ball mill liners are: Rubber liners: These liners are ideal for reducing the impact of the milling process on the shell. They are lightweight, have excellent flexibility, and offer superior resistance to abrasion. Metal liners: These liners are made from highquality alloy steel and are the strongest liners available.

Ball mill Most ball mills, even in primary applications, have a finer ore feed size; this requires some impact but not enough to increase the media consumption or even break the liners. Typically, a ball mill lining has a more rounded profile, often like a sine wave, and the size of the waves is selected based
