Samples arriving in the laboratory often require pre breaking before they can be processed in secondary fine grinding mills; the Laboratory Jaw Crusher is ideally suited for this operation.

These rugged units are capable of crushing the most tenacious of materials; concrete, glass, granite, limestone, ores, quartz, slag and stones.

Normally floor standing units, the Jaw Crushers come as standard with a sample collection tray, they can also be mounted on a frame to accommodate larger containers or fitted into a small pilot plant scheme.

Material is fed into the carbon steel inlet hopper from where it cascades down into the crushing jaws. The action of the eccentric shaft together with the single toggle action both crushes the material and draws it further into the jaws. Output size is determined by the adjustable gap at the bottom discharge end of the jaws.

Standard units are supplied with cast manganese steel jaws and stainless steel lateral wear plates, tungsten carbide and stainless steel jaws are also available and the smallest bench top version can be fitted with Zirconia jaws for non metallic contamination.

Over the years we have supplied many special units with corrosion resistant linings and an all stainless steel version with tungsten carbide jaws for the nuclear industry.
