The Working Principle Of A Jaw Crusher

One of the most commonly used crushing machine is the jaw crusher. It is a heavy-duty machine that is generally used for crushing different kinds of raw materials into smaller pieces. The jaw crushers can be seen in the mining and disposal industry where large rocks need to be crushed into smaller pieces for further use.

There are different jaw crushers on the market, but all of them are designed and are consisted of fixed and moveable parts.

– Fixed parts: the frame is the main fixed part of the jaw crasher. There are also two mechanic build crafts: medium carbon steel and steel welding plate frame.

– Moveable parts: jaw plate, eccentric shaft, bear, belt pulley and other components.

The working principle of the jaw crushers is very simple. Powered by a diesel or gas motor, the jaw crusher brakes materials in a crushing chamber. The materials are pushed inside the chamber from the top opening and when crushed they are released through the bottom opening. The crushing power of the jaw crushers depends on the size of the chamber. The bigger the chamber, the more powerful the jaw crusher. The crushing process can be basically explained as a process where the materials are sandwiched between two jaw plates. The movable jaw plates squeeze and crush the materials into several small pieces.

There are two main types of jaw crushers: double toggle and overhead eccentric jaw crusher. The only difference between these two crushers is the location of the pivot joint. In the overhead eccentric jaw crushers, the pivot joint is located at the bottom of the chamber, while at the double toggle crushers, the pivot joint is on the top. The double toggle jaw crushers are more preferred, simply because these crushers are described as fuel-efficient and easy to operate machines.

The main technical features of the jaw crushers are:

• Simple structure and convenient maintenance;
• Stable performance and low operation cost;
• Even particle and large crushing ration.

The jaw crushers can be used for crushing all kinds of hard materials quickly and efficiently. Powerful and highly efficient, the jaw crushers are essential pieces of equipment in the construction and mining industry. They can be used in combination with other crushing machines for more efficient performance. In most cases, the jaw crushers are used as primary crushing machines in projects where high quality materials are not needed.
