1) Introduction to jaw crusher:

Jaw crusher can be used as the primary crusher to the medium size crushing of various ores and large-size materials , with the anti-crushing pressure of less than 320Mpa.Itis widely used in stone mining, metallurgy industry, building material, highway, railway, and chemical industry.

And the jaw crusher can be divided into two kinds such as coarse and fine crushing .And this series of jaw crusher have complete specifications with the feeding particle size of 125mm-750mm.

This series of jaw crusher can reach the crushing ratio of 4-6 and the shape of final product is even. They are widely applied to crush high hardness, mid hardness and soft rocks and ores such as slags, construction materials, marble, etc. The pressure resistance strength is under 200Mpa, that is, suitable for primary crush. Jaw Crusher can be used in mining, metallurgical industry, construction, road and railway building, conversancy, chemistry, etc.

2) Working principle of jaw crusher:       

The motor transmits power through belt, drives the moving jaw to do periodic motion towards the fixed jaw by the eccentric shaft. The angle between toggle plate and moving jaw plate increases when moving jaw moves . So the moving jaw moves towards the fixed jaw. The stuff will be crushed in this process. The angle between toggle plate and moving jaw decreases when moving jaw moves down, the moving jaw moves leaves fixed jaw by pulling rod and spring, the final crushed stuff will be discharged from the outlet.
