The jaw crusher is a primary crusher. The machine for crushing rocks and other hard and abrasive materials, such as granite, ores or recycled concrete, usually for industrial purposes. The crushing device consists of a fixed plate and a swing plate called jaws between which the rock is trapped and crushed. A motor and a belt transmit the movement to an eccentric shaft that drives the movable jaw by rotation. A spring returns this moving jaw to let the crushed materials gradually descend into the crusher. When the materials are small enough, they fall into the space between the crusher’s two jaws. The crusher breaks the rock into small stones that are used in particular for manufacturing concrete for construction and roads.

Use a rudimentary and reliable technology that does not require much maintenance or engineering knowledge. They are the most popular crushers in the world. Jaw crushers are particularly suitable when the main objective is to reduce large blocks into smaller pieces that can then be processed by other machines.
