What is Jaw Crusher?

Jaw crushers comprise one fixed and one moving jaw. Material is crushed between the movable jaw and the fixed jaw through the application of compressive force produced by the elliptical motion of the movable jaw. The movable jaw, which is supported from the top by an eccentric shaft, is connected to the tension rod and built-in an angled toggle plate that absorbs the cyclic loads in the bottom section.

Types of Jaw Crusher

Primary jaw crushers are used in the first stage of a crushing process for the breaking of large-sized rocks, while secondary jaw crushers with smaller feed openings are used to break smaller ores into finer sizes.

Two different designs of jaw crushers are also produced, being single or double toggle depending on the movement system of the jaw. Single toggle jaw crushers are the most common type, double toggle jaw crushers are for crushing of extremely hard materials.

How Does Jaw Crusher Work?

The material fed to the crushing chamber is crushed when the movable jaw moves towards the fixed jaw by compressing it against the fixed jaw. The movable jaw is driven by an eccentric shaft. Toggle plate attached to the lower part of the mobile jaw acts as a safety mechanism by protecting the jaw crusher from overload situations. The tension rod plays a role in the operation of a jaw crusher by providing the necessary tension and alignment to the toggle plate and the continuation of the cycle.

Advantages of Using Jaw Crusher

· They can be used as a primary or secondary crushers, depending on the feed size.
· The use of jaw crushers in underground applications is convenient and common, as they can be produced with few parts, and are easy to carry, assemble and maintain.
· There are no capacity problems, as the desired capacity can be achieved by using more than one crusher in parallel when necessary.
· They are easy to maintain and affordable.
· The replacement of worn jaws is not time-consuming.

Jaw Crusher Processes Applications

Jaw crushers are used as the primary crushers in the first stage of the crushing process and are preferred when breaking large rocks is the priority rather than achieving high capacity.
Jaw crushers can be used as first-stage crushers in small- and medium-sized plants, as well when secondary crushing is necessary.
The stroke of the jaw generally varies between 20 and 40 mm, That said, the closed side setting at the discharge is as important as the feed opening of the jaw crusher. Closed side setting can be adjusted within certain limits.
