Jaw Crushers Explained

Jaw crushers are machines used for primary and secondary hard material crushing. They use compressive force to reduce the size of raw materials and according to the feeding spread, they can be divided into large, medium and small sized. These machines are designed for heavy- duty applications, however different types of jaw crushers uses different methods to crush the materials and are used for different purposes. Each jaw crush has a specific feeding size, which basically represent the size of the material that the machine is capable to crush in smaller pieces.


Jaw crushers can be used, in departments of mining, construction and demolition field, to reduce the size or large materials such as concrete, stones etc. and are considered the most essential part of the quarrying process as they are simply the most efficient machine to crush rocks.

Typical jaw crushers are consisted of a pair of vertical jaws, one movable and the other fixed, which moves back and forth; a crushing chamber, that is the cavity between the two jaws; a gape, a wide opening at the top of the positioned jaws; a thin outflow opening at the bottom, that can be set to achieve the desired output size. The raw material is gradually crushed, becoming smaller and smaller as it travels downward the outflow opening.

Jaw crushers machines work on a simple principle, allow the input of a wide variety of raw feed material, offer reliable operation, and an incredible versatility, What’s more, their lubrication system have an outstanding performance and maintenance is very simple. They cost less energy, compared to other crushers, and cause less environmental problems such as less noise and dust.

Since many sizes and models are available on the market, choosing the right jaw crane, that will best suit your needs, will involve some factors such as, the type of feed material, the expected productivity and the desired aggregate size. Also buying a jaw crane may seem expensive, but a right type of equipment can improve productivity making it a very cost effective investment.
