Product Introduction
Mill liners are an important customized spare for grinding mills such as cement ball mills. Though the life of a ball mill is relatively long, the spares are under impact and wear in long terms and need replacement once the wear is severe. The mill liners play a key role in protecting the mill shells from natural wear by the grinding balls and materials. It also provides the necessary lift and can transfer the energy for improving grinding efficiency. Different shapes of mill liners can be used to justify the motion state of grinding media to enhance the grinding effect imposed on the materials. It results in higher efficiency, higher output, and lower metal consumption.
SINOMA Zibo offers mill liners applied to cement ball mills, SAG mills, AG mills, etc. grinding mills. We optimize the design and specification to meet the specific demand of our customers.
Advantages of ball mill liners by SINOMA Zibo
Anti-wear.
The service life is longer than that of the ordinary metal liner, and the higher the hardness of the material, the more obvious the advantages of the ball mill liner.
Corrosion resistance.
More corrosion-resistant than ordinary metal steel.
Easy to disassemble.
Simple installation and easy disassembly.
Customizable
Custom manufacture in China as per drawings from customers.
safe and stable
The ball mill liner is more stable and generally does not appear loose or broken.
Less default
The clogging of the discharge grid plate of our casting ball mill liner is less.
SINOMA Zibo mill liners types
According to the part installed: shell liners, head liners, trunnion liners, diaphragm liners, grate discharge liners, special lining systems, etc.
According to the material: metal liners, rubber liners, composite liners, stone or cast stones liners.
According to the shapes： smooth liner, wedge-bar liner, step type shell liner, single wave type shell liner, double wave type liner, studded liner.
smooth liner is used in the fine grinding chamber. The height of the grinding media depends on the static friction coefficient with the liner. The friction coefficient is 0.35 in wet grinding and 0.4 in dry grinding.
Wedge-bar liner is suitable for the first chamber (coarse grinding). It can lift the grinding media to a higher position and produce a higher impact force.
The ribbed liner is similar to the wedge-bar liner. It is a semicircular or trapezoidal rib cast on a flat liner.
Single wave type shell liner is suitable for rod mills.
A double wave type liner with small crests and pitches is suitable for fine grinding chambers.
Studded liners can improve the hoop wear on the liner, and reduce the consumption of the liner and grinding balls.
Step-type shell liner (single step & double step) has the advantages of uniform and consistent lifting height for the same ball layer, and uniform plate surface wear.
ball mill liner material
Ball mill liners can be made from many kinds of materials, such as manganese steel, cast iron, alloy steel, rubber, etc. No matter which type of material is used, the requirements are good impact resistance and wear resistance.
1. manganese steel ball mill liner
The material for the manganese steel lining plate is mainly high manganese steel, which has a certain impact on toughness ( the hardness ranges from HRC20 to HRC25 ). When subjected to a certain impact, the surface of the liner plate can produce cold work hardening to enhance its hardness, so that its hardness can reach HRC40 or more. It is generally suitable for working conditions with small impact force (small and medium-sized concentrating mills). The average service life is 5000-6000h.
2. cast iron ball mill liner
The material for this kind of mill liner is mainly high chromium alloy cast iron, which has strong hardness and toughness, and good wear resistance. It is 6 to 8 times higher than the high wear resistance of manganese steel liners. However, because it is a brittle material, it is mostly suitable for processing ore with soft hardness and less impact in applications.
3. alloy steel ball mill liner
Ball mill liners can be made from many kinds of materials, such as manganese steel, cast iron, alloy steel, rubber, etc. No matter which type of material is used, the requirements are good impact resistance and wear resistance.
