Some ball mills around there are really a black box. There is very little literature on the subject as you mentioned. The object of classifying liners is to keep coarser balls in one section and smaller in the other section. So basically you want high impact energy in one section and lower in the other section.

WhatsApp: +86 18203695377The primary purposes of the liners are to transfer energy to the charge (ore/rock + grinding media), to hold grinding media, and to protect the mill shell from the wear, as well as to prevent liners/lifters and balls from damage.
WhatsApp: +86 18203695377Force analysis. The main function of the ball mill liner is to protect the mill and use the convex peak of the liner to play the ball to grind and crush the material. Therefore, the main failure mode of the liner is abrasive wear under the repeated impact of small energy. Fig. 1 shows the motion diagram of grinding ball and material.
WhatsApp: +86 18203695377Ball Mills. Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation.

WhatsApp: +86 18203695377The ball mill, an intermediate and finegrinding device, is a tumbling drum with a 40% to 50% filling of balls. The material that is to be ground fills the voids between the balls. The tumbling balls capture the particles in ball/ball or ball/liner events and load them to the point of fracture.
WhatsApp: +86 18203695377Ball mill liners play a crucial role in the milling process by protecting the mill shell and reducing wear and tear on associated components. The type of liner used, as well as the size and shape of the mill and milling conditions, are critical factors to consider when selecting the right liner.
