The Structure Improvement of The Double Cavity Jaw Crusher

7/19/2014 11:18:14 AM7/19/2014 11:18:14 AM

To improve the working performance of the double cavity jaw crusher, we have made a improvement on its structure. The new type double cavity jaw crusher is changed its driving machine’s structure into four articulated rods structure. That is to say: the two movable jaw plates is linked to the connecting rod, and make synchronize movement with the connecting rod. Such change greatly improves the jaw crusher’s working performance. Next I will introduce you the structure improvement of the double cavity jaw crusher in detail.

1. Lower the abrasion of the jaw plate. After improvement, the vertical displacement of the movable jaw plates decrease, and its horizontal displacement increase, so the abrasion of the jaw plate lowers.

2. The running is smoother. The connecting rod and rocker low vice are linked by an articulated way, which changes the supporting way of the high vice roll pendulum. The eccentric shaft is set in a lower position, so that lowers the whole machine’s the center of gravity, and the double cavity jaw crusher is smoother.

3. The double cavity jaw crusher’s crushing efficiency is higher. After lowering the position of the eccentric shaft, the toothed plate of the movable jaw is like to make a horizontal movement to the toothed plate of the fixed jaw. Material produces laminated crushing mechanism in the crushing cavity. And the press power of the laminated crushing mechanism is five times bigger than shearing strength, so its crushing efficiency is higher.

4. The double cavity jaw crusher’s production capacity is bigger. After lowering the position of the eccentric shaft, the movement characteristics of the jaw plate have changed. The moving trajectory of each point of the movable jaw tooth plate is more like an oval, which can promote material discharge to eliminate the phenomenon of material clogging. So its production capacity is two times higher than other same specification jaw crusher’s.

5. The particle size of product is even. The double cavity jaw crusher uses deep cavity curved crushing chamber. Since the moving jaw tooth plate similar vertical extrusion breaks materials, so the particle size of product is even and cubic. Materials after crushing can have good shapes, and can better meet the need of production.
