Uses of a Ball Mill Liner

The role of a ball mill liner is to give the mill shell and heads protection against wear and tear thus increasing their lifetime and creating optimal grinding efficiency. The design of a ball mill liner depends on the drilling pattern of the mill heads, the rpm speed of the mill, the maximum diameter of the grinding media and the percentage of media filling. In this way an optimum compromise can be achieved between grinding efficiency and the equipment´s lifetime. Continuous profile studies of the liners help monitor the situation so improvements can be made..

Important Considerations When Choosing a Ball Mill Liner System

The mill lining system is in place for two reasons. The first one is to preserve the mill shell from deterioration caused by wearing down against the mill charge. The second reason is for lifting or sorting and moving the mill contents (material or pulp and ball charge) so that efficient grinding will occur.

Before you choose a mill liner design, you’ll want to mull over your options carefully. Several factors need to be considered, such as the operational parameters and the product and the properties of the grinding media. The liner profile must also incorporate the correct geometric angles to achieve the desired lifting of the mill charge and the correct grinding level. These factors will assist you when deciding on the best liner material and design.

The lining system can be made from steel, iron, composite or rubber. The material chosen depends on the customer’s specific needs and the mill’s operating parameters. Cast metal alloy was traditionally used to make liner plates.

Rubber compounds have been developed to protect the mill shells from excessive wear. New types of cast alloys and highly durable plates can be bonded to rubber. These can stand up well against a high level of abrasiveness. Companies have a higher level of knowledge and experience working with ball mill liners and how they affect the mill’s performance. Companies are now choosing their ball mill liner system based on several criteria, including:

Can the system deliver mill process performance?
Is the system easy to install?
Does the system present any safety concerns?

ROI (return on investment) is another important factor when choosing a mill lining system. Companies are looking at this as a longer-term investment instead of simply considering the initial cash outlay.

Features to Look for in a Ball Mill Liner

How do choose quality ball mill liners ? The best ones on the market will have these features:

Low-weight design: A low-weight design means the ball mill liner doesn’t need as much torque to be effective. Lower weight ball mill liners mean less stress is placed on mill bearings during use. This type is also safer to install since no mill liner handler is needed.
Good sealing properties: When the ball mill liner has outstanding sealing properties, you do not have to be concerned about minerals becoming locked up. The recovery rate for grinding products increases significantly.
Reduced noise: A ball mill liner that can be deployed and will work at a lower noise level means safer working conditions.
