Combo Systems

In a ROCKLABS® customisable Combo System, two or more machines or devices are connected within a single compact machine allowing multiple sampling steps to be combined into one process. ROCKLABS industry-specific range of Combo Systems are designed to reduce human handling errors and increase sample output while improving sample quality and easing labour costs.

BOYD elite® Rotating Sample Divider BRSD

The BOYD RSD Elite combines a double-acting fine jaw crusher with a Rotating Sample Divider for a one-step crushing and splitting process.

In the BOYD RSD , a sample is loaded into a BOYD Crusher and crushed finely before being transported to the Rotating Sample Divider (RSD) via a vibratory feeder. The RSD stands alongside the BOYD Crusher and splits out a pre-set portion for pulverising.

  • Jaws can hold up to 5kg of sample
  • Jaws can be easily adjusted and rotated to extend useful life
  • Two split options available
  • Improved dust and chip control
  • Crushing and splitting in one step
  • Full electrical and mechanical safety
  • Improved ergomoics
