Greatly accelerated liner wear due to high-energy impacts on the liner. For a 5m diameter mill these will be in excess of 8m.s-1, for a 10m diameter mill these exceed 12m.s-1. This causes high chrome liners to spall and crack and they may even fracture. This can reduce liner life from a year to less than a few months.

A ball mill liner is a type of material that is placed inside a ball mill to protect the mill from wear and tear. The liner acts as a barrier between the grinding media and the material being processed, preventing excessive wear and damage to the mill. Ball mill liners also serve to contain the grinding media and prevent it from spilling out of ...

Liners are the essential parts of a mill. They are used to protect the shell and lift the charge in mill's operation. Due to the wear and deformation of liners, the mill needs to stop occasionally so that measurements can be taken for the worn liner to determine how long it can operate without damaging the lifters and mill shell.
