Most mills can be converted from metal liners to composite rubber liners. These liners combine the best characteristics of metal alloys and rubber to obtain a superior design for use in AG/SAG, grate discharge, overflow ball mills and grinding ball mills. By using special alloy steel segments moulded into rubber, composite plates
of contacts and high grinding efficiency especially in the finest range, where ball mills are not effective or cannot reach P80 10 to 40 m. The standard bead materials are ceramics, with a specific gravity (S.G.) of 3.8 to 4.2 kg/dm and bead filling is 50 to 70 % of the mill volume. The mill has a variable speed drive that makes it possible to

2. The ball mill frequency control and speed regulation system makes ball mill running reliably at low speed, ensuring the normal process control requirements. It extends service life of ball mill and reduces maintenance costs. 3. We can set different speed for different time frames according to the requirements of different grinding products.
Investigations were carried out in a laboratory ball mill having the size of DxL 160x200 mm with a ribbed inside surface of the drum. The mill ball loading was 40% by volume, the rotation rate was equal to 85% of the critical speed. Balls were made from steel S4146, extra high quality, having hardness 62 2 HRC according to Rockwell.
