Boundary’s foundations were established designing replacement components for rotary breakers. After decades of experience, Boundary mineral processing products are designed and manufactured to improve wear life and reduce maintenance costs.


Cast Manganese Breaker Plates

Boundary can replace your fabricated rotary breaker plates or optimize cast design for improved wear life.

All Boundary breaker plates are made in proprietary cast manganese steel.

All breaker plates have specially designed through holes to ensure efficient sizing and prevent plugging.

Designed to fit with Boundary’s unique lifters which extend the life and efficiency of plow or lifter.
