Application

Pre-assembled wear set of breaker plate liners with backing plates and clamping wedges, fitted as a block onto the breaker plate body; simplifies liner change-out and guarantees correct gap geometry.

Installation Notes

Support the breaker plate on stands, remove the wedges and old liner set, seat the new liner assembly on the machined face, then drive the wedges home to the specified torque; recheck after one hour of operation.

FAQ

What is the difference between a breaker plate liner and the liner assembly?
The liner is the single wear plate; the liner assembly is the liner plus backing plate, wedges and shims delivered as one ready-to-mount block.
How long does a breaker plate liner assembly last?
Typical life depends on feed abrasiveness and tonnage; inspect at weekly intervals and plan replacement when the face is worn past 50% of original thickness.
Do I need new wedges when I fit the liner assembly?
We recommend fitting new wedges and shims with each liner assembly to ensure tight, repeatable clamping; reused wedges can slip under impact loads.
