The laboratory Aggregate Jaw Crusher is designed for fast crushing of aggregates, ores, minerals, coal, coke, chemicals and other similar materials. Its compact and  rugged construction is advantageous for general laboratory or small pilot plant operations. 

Two jaws of manganese steel are provided in this laboratory jaw crusher. The moveable jaw produces two blows for every revolution, thus reducing over sizing to a minimum. A combination of forward and downward strokes with a rocking action exerts pressure on the coarser material, yet permits the finished material to pass through the jaws.
