Composite liner (rubber + wear-resistant alloy)

The composite liner is a new type of liner developed by Naipu for the intermittent cracking of large semi-self-milling alloy steel liner and the insufficient preload of the large liner bolt, resulting in slurry leakage and over-grinding of the mill. The service life of the lining board and the working efficiency of the mill are well received by users. The structure has metal lifting bar + rubber lining board, metal lifting bar + rubber composite lining board and composite lifting bar + rubber composite lining board, etc., and can be combined and designed according to different working conditions.

1       Features

1.1       The products are composed of natural rubber and wear-resistant metal,with the feature of lmpact resistance abrasion resistance.

1.2       Long service life, high cost/performance ratio.

1.3       Lower noise than that of metal liner.

1.4       Light in weight. Easy for installation and disassembling.

1.5       Energy saving, increase the operating rate.

1.6       Reduce the risk of intermittent cracking of the liners and reduce the issue of insufficient bolt pre-tightening force.

2       Applications
AG, SAG and ball mills in Ferrous or Non-ferrous mineral processing plants. Non-acidic condition. Mostly applied on SAG and ball mills regardless of primary, secondary or regrinding stage.
