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.
LC-27 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. The maximum throughput is approximately 50lb (22kg) per hour at 525rpm. The 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 110V/50-60Hz electrical supplies. A variable speed controller can also operate on 220V/50-60Hz power sources with a slight reduction in speed.
LC-28 3x4in Laboratory Jaw Crusher reduces 3in feed aggregate and rock material to a product with 50% passing 0.25in (6.3mm) sieve. Jaw opening quickly adjusts from 0.375 to 1.5in (9.5 to 38mm). The operation of the overhead eccentric is regulated by the variable speed controller up to 375rpm and quickly crushes material for final testing or to prepare for secondary crushing. Throughput is up to 500 pounds (227 kg) per hour for most materials. High-manganese steel jaw plates can be rotated when worn for extended service life. The 3hp electric motor is 220V and operates on either 50 or 60Hz electrical supplies.
