Liner wear occurs during the grinding process in tumbling mill. It has a significant influence on the overall economic performance of mills. It will be worthwhile to …
The design of rubber mill liners is very specific to the grinding application and will not be covered in this paper. Instead, three design concepts based on rubber as a lining material will be discussed. These are combination liners, rubber grates and rubber covered pulp lifters. Rubber & Steel Combination Liners. Long ago, it was recognized ...
Bradken is a leading engineered grinding mill solutions provider, supported by in-house design and manufacture of high-quality mill liner components to suit AG/SAG, Ball and Rod Mills.

The model of the mill is a combined model consisting of a charge modelled with DEM and the mill structure modelled with FEM. The non-linear finite element code LS-Dyna v971 (2007) has been used for the modelling and simulation of the mill. The mill structure consists of rubber lifters and liners made of rubber and a mantel made of …
