The comminuted ore was then thoroughly mixed and divided, fed to the single-toggle jaw crusher (PEF-60 × 100 mm) and HPGR (CLM-100 × 250 mm, with applied pressure of 5.5 N/mm 2) respectively. The distance between the two rollers of the HPGR was 6.0 mm, so that it matched the width of jaw crusher discharge port.

The material is comminuted by pressure and shearing between the two grinding disks. The material falls automatically on the pre-set grinding gap into the collection drawer. By changing the gap width, the final fineness can be defined from the outside. The device is integrated with Jaw Crusher making the pre- and fine crushing possible in one step.
