A Comprehensive Look At The Types And Applications Of Mill Liners

Proper selection of mill liners holds significant importance, considering the notable drawbacks associated with certain designs.

In particular, large SAG mills have encountered issues such as rapid failure and damage to the mill shell caused by direct impact from the grinding charge. Additionally, inadequate spacing of lifter bars has resulted in unfavorable compromises between lifter bar height and liner life.

It is essential to strike a careful balance when choosing mill liners since they protect the mill shell from wear while transferring energy to the grinding charge. By considering factors like mill size, operating conditions, and material properties, engineers can optimize liner selection and achieve efficient grinding processes with extended equipment lifespan and improved overall productivity.

Let's explore the various types of mill liners and their practical applications in greater detail.

Mill Lining System

A mill is a vital tool for grinding and blending solid or hard materials through shear, impact, and compression methods. Grinding mill machines play a crucial role in various industrial processes.

One integral component is the mill lining system, which serves a dual purpose. Firstly, it protects the mill shell from the impact and abrasion caused by the mill charge. Secondly, it enables the lifting and tumbling of the mill contents, ensuring the necessary grinding action is achieved. These functions are essential in optimizing the efficiency and effectiveness of the grinding process in various industrial applications.

Choosing A Mill Liner

  • SAG Mill Liners. SAG (Semi-Autogenous Grinding) mills are primarily used in the mining industry for grinding large chunks. SAG mill liners can withstand the intense impact of the grinding media and are typically made from durable materials like alloy steel or rubber. These liners are often composed of separate sections that can be easily replaced, allowing for quick maintenance and minimizing downtime.
  • Ball Mill Liners. Ball mills are commonly used in the mineral processing industry to grind various materials into fine powders. Ball mill liners are designed to protect the cylindrical shell and enhance the crushing and grinding process. They are usually made from high-quality steel or rubber, providing excellent wear resistance and impact protection. Different parts and pieces, such as lifters and shell plates, can be used to optimize the grinding efficiency and maximize mill throughput.
  • Rod Mill Liners. Rod mills grind materials by the action of steel rods. Rod mill liners are similar to ball mill liners but are designed to withstand the unique grinding environment in rod mills. These liners are typically made from high-carbon alloy steel or rubber and are strategically placed to prevent excessive wear on the mill shell.
  • Steel Mill Liners. Steel mill liners are widely used in various milling equipment for their exceptional strength and durability. These liners are commonly made from alloyed or high-carbon steel, which provides excellent resistance to impact and abrasion. Steel mill liners are suitable for heavy-duty grinding applications and offer extended service life in challenging environments.
  • Double Wave Liners. Double wave liners, as the name suggests, feature a wave-like profile that helps to lift and cascade the grinding media, leading to efficient grinding and reducing energy consumption. These liners are commonly used in ball mills and provide increased grinding surface area, leading to improved productivity and finer particle size distribution.
