The jaw plate of the jaw crusher
is one of the wearing parts. The wear of the jaw plate brings a lot of maintenance work, which not only consumes time and energy, but also seriously affects the progress of production and reduces the economic benefit of the enterprise. Let's take a look at how to reduce the wear of the jaw plate of the jaw crusher and extend its service life.
1. Install wear-resistant liner. Since the working chamber of the jaw crusher composed of the movable jaw and the fixed jaw bears huge crushing force and the friction of the materials, we can install wear-resistant lining plates on the surface of the movable jaw and the fixed jaw to reduce the friction of the material on the jaw To reduce wear.
2. Install the jaw plate correctly. When installing the jaw plate, it is necessary to ensure correct and stable installation, so that the jaw plate and the surface of the machine are in stable contact, and the work is stable and reliable. Otherwise, it is easy to cause the jaw plate to shift during work, causing the jaw plate to collide with the inner wall of the machine and be seriously damaged.
3. Improve the manufacturing quality of the jaw plate. The higher the hardness of the jaw plate material, the smaller the degree of deformation of the surface material of the jaw plate. The better the toughness of the jaw plate material, the better the fracture resistance. It can be seen that the manufacturing material of the jaw plate should be selected from materials with high hardness and good toughness. During the manufacturing process, the manufacturing quality of the jaw plate should be improved to improve the wear resistance of the jaw plate.
4. Strictly control the input specifications. The nature of the material is obvious to the wear of the jaws, so we should strictly control the input specifications and prohibit materials with excessive particle size from entering the machine. In addition, the feed should be uniform, otherwise it will cause the tilt angle of the lower hopper in the crushing chamber to be too large, and the movable jaw will directly contact and impact the material, which will seriously damage the jaw plate. In addition, it is strictly forbidden to over-iron the machine.
5. Choose a reliable safety device. The toggle protection device is unreliable, so we should choose the electronic safety device, which has the correct and reliable action, without replacing the insurance parts, reducing the maintenance workload and labor strength. And it has the advantages of wide range of applicable models and low cost.
6. Blocking of materials is prohibited. When the material jam occurs in the jaw crusher, the sliding of the material under the compression of the jaw plate increases, which aggravates the wear of the jaw plate, and due to the wear of the jaw plate, the bite angle is further increased, and the material jam is more serious. Form a vicious circle. Therefore, it is necessary to prohibit the blockage of materials in the machine, and clean up in time if the blockage is found.
