What is a jaw crusher machine?
Jaw crusher, invented by Whitney Blake in 1858, is a primary stone crushing machine for reducing minerals or stones into smaller sizes. It is a must-have machine in wide range of fields like mining, quarrying, and construction industries.
The most important parts are jaw plates made of high-manganese-steel, which makes jaw crusher suit for the rock materials with strong hardness.

How many types of jaw crusher?
According to the different movement of the movable jaw, jaw crushers are divided into two types: one is a double-toggle-plate simple swing jaw crusher (simple pendulum jaw crusher), the other is single-toggle-plate compound swing jaw crusher (compound pendulum jaw crusher).
The simple pendulum jaw crusher belongs to large and medium-sized crushing equipment, with a crushing ratio of 3-6.
In the past, compound pendulum crushers were generally made into small and medium-sized equipment, but with the appearance of large impact-resistant rolling bearings, there are now large-scale equipment.

The upper part of the compound pendulum movable jaw has a long horizontal stroke, which is suitable for crushing large pieces of rocks at the upper part. At the same time, its vertical stroke is also long, which has a good crushing effect on materials and is beneficial to discharge materials.
Therefore, the product size of the compound pendulum jaw crusher is fine, and the crushing ratio is large up to 10. With the same specification, the processing capacity of the compound pendulum jaw crusher is 20%-30% larger than that of the simple pendulum jaw crusher.
Due to obvious advantages of compound pendulum jaw crusher and the needs of most customers, Fote Machinery manufactures 4 kinds of jaw crushers are：PE jaw crusher, PEX jaw crusher, HD jaw crusher and CJ jaw crusher.

Working process and the usage of the parts
how does a jaw crusher work?
The movable jaw moving from side to side is hung on the mandrel. When the eccentric shaft is turning, its connecting rod moves up and down, which also drives the two toggle plates to do the same movement. Then the moveable jaw moves from side to side to realize crushing and unloading.
Although the movable jaw bears great broken counter-force and the eccentric shaft and the connecting rod bears little stress, industrial enterprises usually make large and middle size machine to crush hard materials. Additionally, the moving track of the movable jaw is an arc with the mandrel as its center.
The circular arc radius equals the distance from the point to the axis with the upper arc being smaller and the lower arc bigger. The crushing efficiency of the jaw crusher is quite high and the crushing ratio is 3-6.
The main parts and usage of jaw crusher
|Main parts||Practical applications|
|Frame||Keep the machine in place and protect it to reduce the abrasion.|
|Jaw plate||Be used to crush stone materials, fix and protect movable jaw and fixed jaw.|
|Cheek plate||Cheek plates for protection of side plates.|
|Wear plate||Protect the front frame end.|
|Movable system||Be composed of mobile jaw, eccentric shaft and belt pulley, etc. to drive the machine.|
We all know that jaw plate is the most easily worn parts among various of parts installed in jaw crusher. Therefore, in order to use the machine efficiently, the jaw plate should be checked and replaced regularly.
