Jaw crusher is the main equipment of the stone production line, the following is an introduction to the accessories of the jaw crusher:
The jaw crusher is mainly composed of a frame, a flywheel, an eccentric shaft, a toggle plate, a fixed jaw plate, a movable jaw plate, an adjustment device, a movable jaw plate, and a main bearing. Among these spare parts, the main wear parts are fixed and movable jaw plates, toggle plates, eccentric shafts and washers.
1.Fixed jaw plate and movable jaw plate: The crushing chamber of the jaw crusher is composed of a fixed jaw plate and a movable jaw plate. In this case, the fixed jaw plate and the movable jaw plate are in direct contact with the raw material. When working, the fixed jaw plate of the jaw crusher does not move, and the movable jaw plate moves back and forth. In this process, the raw materials are extruded and crushed.
2.Toggle plate: Toggle plate plays an important role in jaw crusher. First, the toggle plate transmits the driving force to support the bottom of the movable jaw plate. Secondly, the toggle plate can protect the jaw crusher. When iron ore and some other foreign matter that cannot be broken enters the crushing chamber, the toggle plate will first separate. At this point, the jaw crusher will stop. In this case, damage to expensive parts can be avoided.
3.Eccentric shaft: The transmission part of the eccentric shaft is composed of movable jaws, eccentric shafts, bearing seats, pulleys, etc., which are mainly used to transmit driving force. Since the axis of the eccentric shaft is not in the middle, it moves on the outer circle. In a jaw crusher, an eccentric shaft and bearing drive a movable jaw plate back and forth to crush the raw material.
