Jaw crusher is a kind of stone crusher machine which is widely used as primary or secondary crusher in stone crushing plant. The purpose is to reduce hard stone material to a small size that it can be transported by conveyors to the next crushing stages.

What is jaw crusher?

Jaw crusher is a stone crushing equipment with high production capacity, large crushing ratio, and high crushing efficiency. It is mainly used for primary and secondary crushing of hard or medium-hard stones. It can process all kinds of ores with compressive strength not higher than 320MPa to medium particle size at one time. It is often combined with cone crusher, impact crusher, sand making machine, etc. to form a complete set of sand and gravel production plant. PE jaw crusher is widely used in mining, metallurgy, chemical industry, building materials, electric power, water conservancy, transportation and other fields.

Working principle 

Jaw Crusher machine uses compressive force to break hard stone material, such as granite, basalt, limestone, gold ore, boulders etc. There two vertical manganese jaw plates create a V-shaped cavity called crushing chamber, where the top of the crushing chamber is larger than the bottom.

The required rock size is determined by the gap between the jaws.

How to choose jaw crusher machine?

1.Model: Jaw crusher model depends on the size of the feeding port. Choosing suitable model is the main factor that buyers need to consider in the initial stage. The size of the model determines the production capacity range of stone crusher.

2.Feed port size: raw material size determines the size of jaw crusher feeding port. The larger the crushed material, the larger the size of jaw crusher feeding port. Large size stones need to choose a large-sized feed port to meet the production needs, and at the same time avoid troubles caused by inappropriate models.

3.Processing capacity: The processing capacity of jaw crushing machine is a key factor to purchase stone crusher. The output per hour is one of the reference factors. It determines the scale of stone production plant.

4.Motor power: The motor power is determined in combination with the overall size of stone crushers. If the equipment is large and the motor power is too small, it will definitely not be able to carry it. Choosing a reasonable electric power will help improve the production efficiency of jaw crusher.
