Composite liners are a new type of liners, particularly engineered by Naipu to address SAG mill leakage due to discontinuous cracks in large alloy liners or loose liner bolts with insufficient pre-tightening force, and over-grinding of material. This type of liners extends the service life of liners and improves the mill grinding efficiency, winning clients' positive comments.
In Australia, China, Brazil, etc, rubber trommels used widely in ball mills and SAG mills.
Rubber and alloy composite liners applied in mines by Naipu clients in China, Australia, Brazil, Pakistan etc.
Results of rubber liners and metal liners applied on 08.5x4m SAG mill at Tongling Dongguashan Mine are as follows.
