Introduction Of Jaw Crusher

The jaw crusher is also called jaw crusher machine,primary crushers,primary jaw crusher or tiger mouth. The crushing cavity of the jaw crusher is made up of dynamic jaw board and static jaw board and finishes the crushing process by simulating the movement of animal jaws. Jaw crusher is widely used to crush medium sized granularity of different ores and bully materials in mining, metallurgy, building materials, highway, railway, water conservancy and chemical industries. The highest compressive strength of the crushed materials reaches 320Mpa.

Advantages Of Primary Jaw Crusher

1. Integrative full-set machine frame

2. Flexibility

3. Low material transportation fee

4. Direct and effective operation

5. Strong suitability and flexible configuration

6. Reliable performance and easy repair

Characteristics Of Jaw Crusher Machine

1. The jaw crusher machine solves the high running rate and little maintenance time problems caused by the low yield of the traditional limestone crushers.

2. The jaw crusher machine can break bulk limestone with the maximum grain diameter of 1000*1200mm, which solves the limestone supply tension problem meanwhile the bulk limestone is not available.

3. The two materials are mixing evenly, so the desulfuration limestone is added with increasing quantity as high as 60%, thus saving the raw materials cost.

4. The jaw crusher reduces the power consumption and the power for processing one ton of limestone decreases by 1-2KW/t. This will save 0.1 million RMB electric charge per year.

Working Principle Of Primary Crushers

The dynamic 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 thrust plates to do the same movement. Then the dynamic jaw moves from side to side to realize crushing and unloading. The jaw crusher adopts crank link mechanism. Although the dynamic jaw bears great broken counter-force and the eccentric shaft and the connecting rod bears little stress, industrial enterprises usually make large sized machine and middle sized to crush hard materials. Additionally, every moving track of the dynamic 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 low and the crushing ratio is 3-6.
