Advantages of Polyurethane Mill Liners

• Excellent Impact Absorption：Rubber elasticity absorbs grinding impact and reduces liner stress concentration.
• Excellent Noise Reduction：Rubber liners significantly reduce grinding noise compared with steel liners.
• Reduced Vibration Damage：Rubber damping reduces vibration transmission to mill structures.
• Better Suitability for Medium Impact Conditions：More tolerant to fluctuating impact loads than polyurethane liners.
• Lightweight & Safer Installation：Lighter than steel liners and easier to replace.
• Reduced Liner Cracking Risk：Rubber flexibility reduces brittle failure risk.
• Lower Maintenance Workload：Reduced vibration damage improves operational stability.

Grinding Condition Analysis

• Proper rubber liner selection requires engineering analysis of:
• Ore hardness
• Abrasion mechanism
• Impact intensity
• Grinding media size
• Slurry concentration
• Throughput capacity
• Mill rotational speed
• Wet or dry grinding conditions
• Rubber liners are generally more suitable for:
• Medium-impact grinding
• Wet slurry systems
• Noise-sensitive operations
• Systems requiring vibration reduction
• Rubber liners are generally less suitable for:
• Extremely sharp fine-particle abrasion
• Severe coarse crushing impact
• Very high-temperature grinding conditions
