Composite Liner – Application Fields of Steel-Rubber Composite. Various large, medium and small grinding mills (pebble mills, semi-autogenous mills, ball mills, etc.) are the core equipment used in mineral processing and grinding processes worldwide. The quality of wear-resistant liners installed inside the mills directly affects the operation rate and grinding efficiency of the mills, and further influences the economic benefits of the entire mine. Steel-rubber composite liners are composed of high-strength steel and rubber. When applied to large-scale mills, they effectively extend the service life of existing mill liners without reducing grinding efficiency. Advantages: 1. Reduce noise by more than 20 decibels. 2. Cut unit grinding power consumption by at least 3%. 3. Double the service life of liners and improve equipment operation rate. 4. Lower the unit consumption cost of liners. 5. Reduce bearing load of mills and prolong equipment service life. 6. Alleviate labor intensity and improve installation efficiency. 7. Reduce carbon emissions and comply with national environmental policies.
