Jaw crusher is a type of crushing equipment that uses compressive force to reduce the size of raw materials. The jaw crushers have become an essential part of the quarrying processes, as they are simply the most efficient units for crushing rocks. Most commonly, the jaw crusher are used for hard primary and secondary crushing, and less commonly for recycling rock or concrete. A typical jaw crusher is composed of a couple of jaw plates, one movable and the other fixed, a set of vertical jaws, also one movable and the other fixed. However, the movement of the jaw plate and the vertical jaw is limited to back and forth only.
The free space between the two jaws is known as crushing chamber, in which the crushing process takes place. In the crushing chamber, the jaw crusher places the material about to be reduced to the desired size and using compressive force, the jaws are pressing the material until its size is reduced enough to pass through the tiny hole at the bottom. The jaw crusher is specifically designed for heavy-duty applications with steel/iron design. The jaws are constructed exclusively from cast steel and are equipped with liners that are rigidly made from quality steel.
As well as each other crusher type, the jaw crusher is classified to few types, based of the pivoting position of the swing jaw. So, the three jaw crusher types are:
The blake jaw crusher is also a widely utilized crusher, since its first version in the early 1860s. Unlike the dodge jaw crushers, these jaw crushers have a variable discharge area and a fixed feed area. There are two types of blake jaw crushers: single toggle and double toggle jaw crushers. These two blake jaw crushers have few differences and are suggested for different applications.

- Dodge crusher with the swing jaw positioned lower.
- Blake crusher with the swing jaw positioned upper.
- Universal crusher with the swing jaw positioned intermediately.
