Our jaw crusher is a high efficient and energy saving machinery which introduces successful experience of the same machines home and abroad. These series of jaw crushers are widely used in mine, metallurgy, construction, road building, railway, water conservancy and chemical industry. They feature high crushing ratio, good shape in product, simple structure, reliable performance and low operation cost. They are ideal choice for primary crushing.

Operation principle of jaw crusher:

The motor drives the belt and the grooved wheel, which connect the eccentric shaft. Through the movement of eccentric shaft, the movable jaw plate moves up and down. When movable jaw plate moves up, the angle between it and toggle plate will be enlarged, so the movable jaw plate will be close to fixed jaw plate. Then, the materials will be pressed and crushed; when movable jaw plate moves down, the angle between it and toggle plate will be reduced, movable jaw plate will moves away from fixed jaw plate due to the tension rod and springs. At this moment, the crushed materials will be discharged at discharge opening. With moving of motor and periodical movement of movable jaw plate, material will be crushed and discharged gradually, so that batch production will be reached.

Process of Stone Production Line:

Big materials are fed to the jaw crusher evenly and gradually by vibrating feeder through a hopper for primary crushing. After first crush, the material will transferred to impact crusher by belt conveyor for secondary crush; the crushed materials will then transferred to vibrating screen for separating. After separating, the parts that can meet standard will be transferred away as final products, while the other parts will be returned to impact crusher, thus forming a closed circuit. Size of final products can be combined and graded according to customer’s specific requirement. We can also equip dust catcher system to protect environment.

Process of Sand Production Line:

The stone material is sent regularly by the vibrating feeder to the primary jaw crusher, the crushed material is sent to the secondary jaw crusher to be crushed again. The crushed material is sent by belt conveyor to vibrating screen to be separated. The material, whose size is suitable for the feed size of the sand making machine, can be sent to the sand making machine. The unsuitable material should be sent back to the secondary jaw crusher to be crushed again. The crushed material from the sand making machine is sent back to the vibrating screen to be separated. The suitable separated sand, which is the final product, should be sent to the sand washing machine to be cleaned, and then sent by the belt conveyor. The unsuitable separated sand should be sent back to the sand making machine to be crushed again. The producing line forms two closed cycles. The producing line can be changed according to the customers’ requests.

Process of Powder Making Production Line:

Materials first enter jaw crusher to be crushed to smaller size. Then they are lift to storage room by elevator. Vibrating feeder will feed materials into grinding chamber evenly and gradually. After being grinded, the powder will be blowed to cyclone by blower. Then the material will be transferred to storage room through pipes, and then will be discharged as final products. The whole process works in a negative pressure environment. First, through pipes, the air from the blower enters the cyclone collector above the storage room along with powder, and then returns to the blower through return pipe. In the way, air can be recycled. There is a powder locking equipment under the cyclone, which isolates the outside positive air pressure and the negative air pressure inside cyclone. And this ensures high productivity. In addition, the residual air and dust under the main unit will be transferred to dust catcher equipment through pipes and be cleaned there. The clean air will be discharged so that environment will be protected. These jaw crusher are recommended by leading consultants in this field and are used by hundreds of customers all over the world.
