The selection of the rock breaker should reflect your site requirements. Selecting a boom which is too light will cause increased maintenance and reduce the overall life of the stationary rock breaker system. The core factors that determine a functional boom system are; the type of crushing plant, the tonnage capacity of the plant and the size and hardness of materials being processed.

  • Light duty: soft to medium rock hardness, intermittent breaking with little or no raking.
  • Medium duty: medium rock hardness, intermittent to moderate breaking with some in-line raking.
  • Heavy-duty: medium to hard rock, moderate to continuous breaking with in-line and side raking.

Our experienced engineering team are on hand to advise and offer technical support to assist in selecting a boom system to best meet the technical requirements at site. They will endeavor to understand production requirements, specifying equipment that will increase material production and personnel safety.
