HLY-MNT-02: Twin-Shaft Mixer Wear Liner Replacement, Clearance Adjustment & Seal Greasing

1. Blade-to-Liner Operating Clearance Adjustment

Inspect gap between blade tips and curved wear liners weekly; maintain between 3.0 and 5.0 mm.

If clearance exceeds 8.0 mm, loosen locking bolts, extend blade along slotted hole to restore 4 mm gap, and re-torque to 350 N·m.

Original liner thickness is 18 mm; replace when worn down to $\le$ 5 mm or if cracked.

Clean mounting seat before fastening new high-chromium liner tiles; use high-tensile countersunk bolts with threadlocker.

Confirm automatic grease pump reservoir is filled with NLGI 00 extreme-pressure lithium grease.

Ensure fresh grease continually beads from all 4 shaft-end relief ports during mixing, confirming positive counter-pressure against slurry ingress.
