Viper help increase production

Roadstone Galway have recently installed a Viper Rockbuster on their primary crusher to mechanically clear any blockages in the crusher and feeder.

The company had three main priorities :

  • the boom had to be flexible enough to reach down into the crusher but must not go any closer than 450mm from the rotor
  • the boom had to reach into the hopper to clear blockages
  • the steelwork that supports the boom was not to obstruct cleaning and access to the crusher for maintenance.

Viper installed a Rockbuster 80/3 designed specifically for applications with access problems to impact crushers.

To fulfil Roadstone Galway's first priority the three-arm system of the Rockbuster was controlled by accurate measurements and the fitting of restrictions in the cylinders. The second objective was achieved as the three arms have an overall length of 7.1m which is enough to reach the hopper. To maintain access around the crusher for maintenance and cleaning, Viper offered a tower frame-type structure with steelwork on one side only and a cantiliver frame to position the boom centrally over the crusher.
