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.

Ball Mill Liner components: Our ball mill liners solutions can be fitted with MultoMet composite lifter bars, shell plates and head plates. The MultoMet range utilises Hardox 500 wear-resistant steel, attached to the leading edges of the lifter bar array and embedded within shell plates and head plates, ensuring maximum abrasion and impact resistance.

Advantage #2 – Composite liners resist pegging and peening. Mill lining suppliers have the flexibility to design liners with less components when they use composites. This has the benefit of reducing joints between liners and minimising joint gaps which occur with steel liners due to casting tolerance. The disadvantage of steel liners …

The impact energy of grinding ball and the moving state of medium are the direct factors that affect the grinding effect of ball mill. The structure of liner is closely related to both.

The ball mill rotates clockwise at various constant fractions N of the critical speed of 19.5 rpm, at. Charge behaviour. Fig. 1 shows typical charge shapes predicted for our 'standard' 5 m ball mill and charge (described above) filled to 40% (by volume) for four rotation rates that span the typical range of operational speeds.

Force 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.

Discrete element method (DEM) modelling has been used to systematically study the effects of changes in mill operating parameters and particle properties on the charge shape and power draw of a 5-m ball mill.
