Its working process is as follows: the motor drives the belt and pulley, causing the eccentric shaft to move the movable jaw up and down. When the movable jaw rises, the angle between the toggle plate and the movable jaw increases, pushing the movable jaw plate toward the fixed jaw plate to compress and crush the material. When the movable jaw descends, the angle decreases. Under the action of the tension rod and spring, the movable jaw plate moves away from the fixed jaw plate, allowing the crushed material to be discharged from the lower opening of the crushing chamber, completing […]
