A brief introduction of jaw crusher:
The jaw crusher appeared in 1858, and was first widely used in road construction and later applied to mining. The jaw crusher features uniform particle size, simple structure, reliable operation, easy maintenance and economical operating costs.
In addition, it has been widely used for the coarse, medium and fine crushing of various kinds of ores and rocks whose compression strength is 147-245 Mpa in many industrial departments such as metallurgy, chemistry, building material, power plant and transportation.

In recent years, in order to meet the needs of crushing high-strength, high-hardness micro-carbon ferrochrome in the metallurgical, mining, construction and other industries, the Fote R&D laboratory has specially developed a strong-force jaw crusher.
As an industry pioneer in China mining machinery, Fote Heavy Machinery has continuously innovated, and has launched 4 types of jaw crushers：PE series, PEX series, German version and CJ series European version jaw crusher with reasonable prices and high quality.
At the same time, when considering the different needs of different users, our company also launched a Mini-type jaw crusher to meet the needs of small crushing.

How does the jaw crusher work
Working process and the usage of the parts
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.

How to install and replace the jaw plate
1. Replacement of the jaw plate
- Step 1: Remove debris around bolts and wedges;
- Step 2: Loosen the fixing nut and remove the sleeve;
- Step 3: Install the striker nut on one side until it hits the wedge;
- Step 4: Use a hammer to strike until the wedge leaves the original position;
- Step 5: Remove the striker nut and attach it to the other side;
- Step 6: Tap the nut with a hammer until the wedge leaves the original position;
- Step 7: After the wedge leaves the original position, the jaw plate can be removed.
2. Installation of the jaw plate
When re-installing the jaw plate, make sure that the surrounding areas of the wedges are cleaned. You should apply grease to the contact surfaces of the wedges and the cones, such as copper corrosion-resistant grease, which will help dismantle them in the future.
After the preparation, put jaw plate in and ensure that the bottom of jaw plate is properly seated, then put modules in. The plate is hung until wedge blocks are locked and equally tensioned to ensure that the jaw plate and its bracket are tightly attached.
