Product introduction
Jaw Crushers are ideal for pre-crushing of very hard, hard, medium-hard, brittle, tough and temperature-sensitive materials, and widely used inmining, construction,chemical industry, metallurgy and so on. Thestone is crushed under high pressure between one fixed and one movable crushing jaw.
 
Working principle
The crushing way adopts moving and squeeze principle. The movable jaw moves up and down by the effect of eccentric shaft. When the movable jaw elevates, the angle between elbow and movable jaw becomes larger, and this impulses the movable jaw close to the stable jaw, while the material can be pressed and chopped into pieces; when the movable jaw falls, the angle between elbow and movable jaw becomes smaller, movable jaw gradually leaves far from the stable jaw under the effect of pull rod and spring. Then, the broken material can be discharged from the down-mouth of crushing chamber.
