Composite liners are a new type of liner specially developed by Naipu to address issues such as intermittent cracking of alloy steel liners in large semi-autogenous grinding (SAG) mills and insufficient pre-tightening force of large liner bolts, which lead to slurry leakage and mill shutdown, as well as over-grinding in mills. They significantly improve liner service life and mill operating efficiency, and have been well received by customers. Structural configurations include metal lifter bars + rubber liners, metal lifter bars + rubber composite liners, and composite lifter bars + rubber composite liners, etc., which can be designed in combination according to different operating conditions.

Performance Characteristics of Composite Liners
1. Impact resistant and wear resistant.
2. Long service life and high cost-effectiveness.
3. Lower noise than metal liners.
4. Lightweight and easy to install and remove.
Application Scope
Discharge end lifters, grate plates, shell liners, etc. for semi-autogenous (SAG) mills and autogenous (AG) mills;
- Complete liner sets for primary and secondary ball mills, etc.
