Jaw crusher. The name jaw comes from the mechanical action of the crusher breaking up rock and concrete in the same way our jaws break up food. One fixed and one swinging plate allows the crusher to easily break up concrete slabs and other hard, abrasive materials. Crushed output will be more slate-like with an oblong shape because it relies …
