New generation rotary stone crusher, pew series jaw crusher is born with innovative significance. It is newly designed and improved by our experts on basis of their more than 20 years' crusher manufacturing and design experience. The unique design concept makes this series rotary stone crusher achieve perfect combination between crushing efficiency and operating cost. Meanwhile, it has a wide range of application, particularly is suitable for crushing hard rock, such as basalt, river pebbles.
rotary stone crusher working principle:
The structure of rotary stone crusher: main frame, eccentric shaft, a large belt pulley, fly wheel, swing jaw, side guard plate, toggle plate, Rear bracket, adjust gap screw, reset spring, and fixed jaw and swing jaw board etc., and the toggle plate also plays a role of protection.
The motor transmits power through belt and belt pulley, drives the swing jaw surround the eccentric shaft do periodic motion. The angle between toggle plate and swing jaw increases when swing jaw moves up., which makes the moving jaw get closes to the fixed jaw.
At the same time the material is squeezed, rubbing, grinding and other multiple broken. The angle of Jaw Crusher between toggle plate and swing jaw decreases when swing jaw moves down, the moving jaw of Jaw Crusher moves away from fixed jaw by the pulling of rod and spring, the products after crushing will be discharged from the outlet of Jaw Crusher.
