Grizzly Rockbreaker Applications

Underground mining operations typically use a steel grate called a grizzly to size material before it enters an ore pass. Material that is too large cannot pass through the openings in the grizzly and are left on top of the grizzly to be broken by a Rockbreaker, while the smaller material is allowed to pass through the grizzly down the ore pass.

 

Grizzly applications are extremely harsh by nature. The boom is subject to high degrees of in-line and side raking, combined with various sizes and amounts of oversize. BTI’s grizzly booms are designed with wide boom cross sections, extra large pins and reinforced high tensile steel plates. All designed to handle complex loading to the boom.

 

 

Grizzly Coverage:

The boom you choose to carry the selected breaker depends on its ability to provide full coverage of the area where material will require breaking, racking or clearing.
