A current trend in mineral beneficiation is to leverage grinding efficiency gains associated with large diameter mills. However, operating mills of increasing diameter presents significant liner service life and maintenance challenges. To meet these challenges, Kosga offers composite mill rubber liners.

Kosga composite mill rubber liners combine the most desirable properties of rubber and steel to maximum advantage. This combination allows the use of more wear resistant alloys of iron and steel than can be used in a conventional metallic lining, as the rubber substantially dampens the impact forces and also results in a lower lining weight. This makes Kosga mill linings an outstanding solution, particularly in heavy applications. The rubber imparts flexibility, facilitates maintenance, and in combination with extremely hard metallic inserts maintains an efficient profile over the entire lining life.

AG and SAG use lift bars of equal height or height. The latter with good shape retention has good performance at very low cost. The lift bars with equal height can reduce maintenance times and inspection wear rate. The short downtime is also reduced correspondingly. Providing is suitable for most Ag and sag wide spacing lining. Its characteristics are as follows: the number of lining parts is small; the replacement time is short; the lining height can be increased as required to achieve longer service life; the angle of lifting plate is extended to improve the performance.

composite mill rubber liners perform best with features from both rubber and steel. Rubber relieve continuous impact. composite mill rubber liners can be made of alloy steel with higher hardness and wear resistance. So far, composite mill rubber liners have demonstrated excellent in primary grinding applications, such as ball mill, rod mill, Ag and SAG mill.
