BB6550 Breaker boom

Sandvik BB6550 breaker boom is typically used in quarries and mines to improve the productivity of stationary crushers by feeding material into the crusher and by raking the hopper area.

Medium range booms are designed to endure tougher duty cycles and can also be used in more demanding applications, such as underground grizzlies. The triangular boom design of Sandvik medium range booms optimally combines a light weight with a high capacity. The circular shape of the boom pedestal effectively optimizes the stress distribution and foundation structures.
