Introduction of Small Stone Jaw Crusher :
Small Stone Jaw Crusher are based on years of product development.The continuous improvement and refinement has made them the preferred Jaw Crusher among professionals and our customers.
The series of our Jaw crusher are 6 models which can meet most capacity requirements in primary and secondary crushing, at the same time, with low power consumption and easy maintenance.Every feature of these machinery has been carefully designed to provide superior quality and performance.Jaw crushers are widely applied in areas of mining, metallurgical, construction, smelting, hydraulic and chemical industries, etc.
Characteristics of Small Stone Jaw Crusher :
1, unique structure of jaw head, seal guarantee, extend working life of the bearing.
2, integral casting of the bearing base, adopt the new assembly process to perfectly match with the frame , increase the radial intensity.
3, adopting deep cavity "V" type structure, to greaten the feeding size (compared with ordinary jaw crusher) and increase the capacity.
4, adjust the structure of the discharging opening,which is convenient, quick, safe
5, tension bar protection device, more safer
6, increase the bearing capacity of the jaw head, make the machine more efficient, safe, extend the working life of the bearing and main shaft.
7, new oil road design, matched with the oil pump, more simple and efficient on the operation and maintainance.
8, unique flywheel design, effectively reduce the vibration, running more smoothly.
Working principle of Small Stone Jaw Crusher:
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.
