Types of Mill Liners. There are several types of mill liners available, each with its unique properties and benefits. The most common types of mill liners include: Steel Liners. Steel mill liners are the most widely used type of mill liner, and they are typically made of highstrength steel alloys such as manganese steel, chrome steel, or Nihard.
effect of liner type and wear on ball mill grinding efficiency and throughput. This thesis provides a comprehensive analysis of key mill operating parameters and addresses the following key research question: how does liner type, lifter face angle, and liner wear affect mill grinding efficiency?
Ball Mill Principle. The ball mill machine is mainly composed of cylindrical cylinder, end cover, bearing and big gear ring. Cylinder: The cylinder is filled with a ball mill grinding media (steel balls or steel cylpebs) with a diameter of 25mm150mm. The loading capacity is 25%50% effective volume of the whole cylinder.
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.

A secondary mill will require the high surface contact with more of the grinding motion that the lower cascade brings. This means that the secondary mill will have LOW PROFILE ROD MILL LINERS in them. If it is a ball mill being used as the primary grind the size of the grinding media will be increased, this is to increase their impact. A HIGHER ...
