The jaw crusher is a crushing machine composed of two jaw plates, a movable jaw and a static jaw, to complete the material crushing operation by simulating the motion of the two jaws of animals. It is widely used in the crushing of various ores and bulk materials in mining and smelting, building materials, highways, railways, water conservancy and chemical industries.
Jaw crushing jaw plate and guard plate: toothed jaw plate is installed on the working face of the movable jaw and in front of the opposite frame, and side guard plates without teeth are installed on the two inner walls of the frame to form a square cone crushing chamber. The jaw plate and the guard plate are in direct contact with the crushed materials, and are subject to strong crushing extrusion force and friction and wear, so they are generally made of wear-resistant materials. ZGMn13 or expensive high manganese nickel molybdenum steel is commonly used, and white cast iron is also commonly used as a substitute for small jaw crushers in small and medium-sized plants.
Jaw crusher thrust plate (lining plate): supports the movable jaw and transmits the crushing force to the rear wall of the frame. When there is an adjustment device at the rear end of the thrust plate, it can be used to adjust the size of the discharge opening. In the design, the gray cast iron material is often used to determine the size of the size according to the condition that it can fracture by itself when overloaded. The thrust plate is also a safety device, which can automatically stop working when there is an unacceptable overload in the work, so that the discharge port is enlarged, so as to protect the movable jaw, eccentric shaft, frame and other valuable parts from being damaged. Therefore, do not change the material and size of the original image without any special reason.
