- Jaw Crushers


The CMB range of Rockmonster jaw crushers are modern, cast steel, all roller-bearing machines. Designed to cope with some of the worlds' toughest aggregates, this is a machine developed specifically for heavy duty quarry work.

The crusher features stepless mechanical/hydraulic adjustment enabling the operator to quickly change settings. There are no shims to change or bolts to re-tighten during the adjustment procedure.

Welding has been kept to a minimum in the design. The massive front wall and cross beam are special heat treated castings that are bolted and pinned into position. This method of construction avoids stress concentration often found in welded components.

Product features:

  • High outputs of good product shape
  • Unattended operation
  • Fast, simple adjustment
  • Minimal maintenance
  • Large unobstructed feed opening.
