Laboratory Jaw Crushers are designed for economic size reduction of typical aggregates and common minerals at an output scaled for laboratory testing. Adjustable jaw openings allow close control of output size. High operating rpm promotes efficient size reduction with lower dust generation compared to other crushers and pulverizers. Crushers are mounted on sturdy welded-steel base frames with CSA-rated electric motors and are fully equipped with pulleys, feed hoppers, and safety guards. Replacement Jaw Plate sets are available.

The 2.25x3in Laboratory Jaw Crusher reduces 2in (50mm) aggregate, ore and rock materials to a product with 80% passing a No. 14 (1.4mm) sieve. Jaw opening easily adjusts down to 1mm minimum to closely control output size. Maximum throughput is approximately 50lb (22kg) per hour at 525rpm. Rate of operation is regulated by the variable speed controller. Jaw plates are high-impact, wear-resistant AR450 steel. It has a 1hp electric motor. Electrical cord and plug are included for operation on 115V/60Hz electrical supplies. Variable speed controller can also operate on 220V/50Hz power sources with a slight reduction in speed.
