Jaw crushers reduce large rocks or ore by means of compression. Mechanical pressure is applied using the crusher's two jaws; one is fixed while the other makes an eccentric movement. There are also primary and secondary types of these crushers. Jaw crushers are one of the most commonly preferred crushers due to their ability to crush all ...

The size of a jaw crusher is measured by the top opening of the crushing chamber. For example, a 48" x 42" jaw crusher measures 48" from one crushing jaw to another and is 42" across the width of the two crushers. The primary applications for using jaw crushers are: Crushing different kinds of ore; Reducing building rubble to pieces
