How a Jaw Crusher Works and What It is Used For



A primary piece of equipment in the mining industry, a Jaw Crusher is a standard for any worksite. It is a compression type crusher and is popular for its ability to be used in many applications, breaking down a range of materials and sizes. A good example would be Bost Group’s Gasparin GI 129C, whichclients use for projects across Australia and internationally.

How a Jaw Crusher Works
A Jaw Crusher uses compressive force to break down materials. It uses two jaw dies. One jaw is stationary and v-shaped while the other moves to crush the material between them. As the material in the Jaw Crusher is broken down into smaller parts, the discharge is then forced through a gap at the bottom of the crusher. The remaining material is only discharged once it is small enough to exit the crusher.

Types of Crushers:

Crushers are classified into three types, based on the stage of crushing that they each accomplish. These three stages are Primary Crusher, Secondary Crusher and Tertiary Crusher. The Primary Crusher receives material directly from the run-of-mine (ROM), and after breaking it down into smaller material, it is sent to the secondary crusher. The Secondary Crusher breaks it down into even smaller material before sending it to the Tertiary Crusher, and so on.

What a Jaw Crusher Is Used For

Jaw Crushers are Primary Crushers and are generally used for large-sized materials, reducing them into smaller rocks, rock dust or gravel. They are commonly used for mining materials such as ore. They are a popular alternative to Gyratory Crushers because Jaw Crushers can handle large amounts of materials quickly. They are also chosen for their smaller size and mobility, being able to be easily transported and placed in tight spaces such as underground sites.
