Gyratory Crusher Rockbreaker Applications



 

Big jobs need big booms and breakers. BTI’s wide range of gyratory booms allow full breaker coverage within the rock box and mouth of the Crusher. BTI’s complete line of large hammers are designed specifically for gyratories to quickly eliminate any bridging or clogging, restoring consistent material flow to the crusher.

The gyratory crusher is the mainstay of medium to large duty crushing plants. Typically material is brought to the crusher by large haulage trucks and dumped into a rock box. The gyratory crusher is located at the bottom of the rock box. Material is crushed between the eccentrically mounted rotating crushing cone and the fixed, tapered crushing throat.

The Rockbreaker is typically mounted in-line with the upper support of the rotating cone called the spider. This provides superior maneuverability of the Rockbreaker within the gyratory throat. The boom is typically sized to allow full range of motion over the working range of the rock box. The reach should be deep enough to allow the breaker to enter the gyratory for material breaking and concave removal applications.



 

Crusher Coverage:

The vertical breaker coverage zone shown in the gray area has superior maneuverability and performance allowing the boom and breaker to operate without subjecting the boom to undue stress. The boom should be sized so the majority of breaking and raking operations can be done within the zone of the vertical breaker coverage zone.

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.

Chart - BTI Hydraulic Breaker sizing for Gyratory Crusher Applications

Breaker power required is determined by the hardness, toughness and size of material to be broken. The size of your crusher or grizzly also affects the selection size of breaker.
