Mn18Cr2: work-hardens from ball impact to 500–550 HB — the workhorse for cement and mineral processing. Cr-Mo alloy: for severe abrasion in SAG/pebble mill applications where impact energy is lower but abrasive loading is higher. The material choice depends on your ball size, mill speed, and feed material hardness.

Full reline (all shell liners + end liners + diaphragm): at major maintenance intervals when all components have reached 50%+ wear. Partial reline (single section): only in emergency repairs where one section failed prematurely. Partial relines leave mismatched wear profiles that cause uneven grinding media trajectories.

Two signs: (1) product top size exceeds specification (oversize particles in mill discharge), (2) recirculation load increases as coarse particles bypass back to the mill. Replace diaphragm and discharge grate plates when slot width exceeds design by 2–3 mm.

Every full reline set ships with a numbered installation drawing showing each liner piece position, orientation, and bolt torque sequence. Liners are individually labeled with position numbers matching the drawing. This eliminates trial-and-error installation and reduces reline downtime.
