Protection of the mill shell and the end walls from the aggressive impacting and abrasive environment inside a mill is well known as the primary purpose of mill liners (Powell et …

1. Liners protect the outer shell of the mill from wear - liners are renewable. 2. Lifters prevent slipping between the medium and slurry charge in the mill and the mill shell. Slippage will consume energy wastefully but more importantly it will reduce the ab ility of the mill shell to transmit energy to the tumbling charge.

The objective is to achieve a more efficient operation and increase the production rate as well as improve the run factor. It is lined with classifying-type mill shell liners and provided with finer ball charge.

Design of cement mill liners There are several types of cement mill liners: feed-end-liners, lifting-liners, classifying liners.They all have some features in common. Magotteaux determines the optimum design and alloy for cement mill liners to give the best mill protection. This is done according to a variety of factors such as shell liner type, rotation speed, maximum ball …

Rod mill liners are subjected to severe impact. Premature breakage and scrap loss are reduced by correct selection of liners for the specific grinding duty. Additional benefit results from use of a backing material, such as rubber between the liners and the mill shell. Single wave liners are recommended for larger size balls (50mm/2.5″ and ...

Through Welding Alloys technology, cement plants across the globe have benefited from reduced VRM grinding component wear, longer lasting mill shell liners, roller hub guards and various other products and solutions to enable them to increase productivity, optimise mill efficiencies and simultaneously reduce costs. ifecycle

• The selected Shell Provisional will be identified through a size and a two letter code (e.g. 50 HH). There are different inner diameter Implant sizes available for each Shell size. The Provisional Liner will be identified by letter code matching the Shell diameter and desired inner diameter (e.g. 32 HH).
