How can we reduce the maintenance cost of jaw crusher

The jaw plate of jaw crusher is one of the wearing parts, and the wear of jaw plate brings a lot of maintenance work, which is not only time-consuming and labor-intensive, but also seriously affects the production, and reduces the economic benefits of the enterprise. Here we come to know how to reduce the wear and tear of the jaw plate of the jawbreaker and prolong its service life.

1. Install wear-resistant liners. Since the working chamber of jawbreaker composed of movable jaw and fixed jaw is subject to huge crushing force and friction of materials, we can install wear-resistant lining plate on the surface of movable jaw and fixed jaw to reduce the friction of materials on the jaw plate and reduce the wear and tear.

2. Install the jaw plate correctly. When installing the jaw plate, we must make sure that it is correctly and firmly installed, so that the jaw plate can contact with the surface of the machine smoothly and work stably and reliably. Otherwise, it is easy to make the jaw plate shift in the work, resulting in serious damage caused by the collision of the jaw plate and the inner wall of the machine.

3. Improve the manufacturing quality of the jaw plate. The higher the hardness of the jaw plate material, the smaller the deformation of the jaw plate surface material. 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 choose the material with high hardness and good toughness, and in the manufacturing process, the manufacturing quality of the jaw plate should be improved in order to improve the anti-wear ability of the jaw plate.

4. Strictly control the feeding specification. The nature of the material is obvious to the wear and tear of the jaw plate, so we should strictly control the feeding specification, and prohibit the material with too large particle size from entering the machine. In addition, the feeding material should be uniform, otherwise it will lead to too big tilt angle of the lower hopper in the crushing chamber, and the movable jaw will contact with the material indirectly, which will cause serious damage to the jaw plate. In addition, the machine should be strictly prohibited from over-iron phenomenon.

5. Use reliable insurance device. Elbow plate protection device is unreliable, so we should choose the electronic insurance device, with correct and reliable action, no need to replace the insurance parts, reduce maintenance workload and labor intensity and other advantages. And has a wider range of applicable models, low cost and other advantages.

6. Prohibit material blockage. When there is material blockage in the jawbreaker, the sliding of material under the extrusion of jaw plate will increase, which will aggravate the wear and tear of the jaw plate, and due to the wear and tear of the jaw plate, the meshing angle will be further increased, and the blockage of material will be more serious, which will form a vicious circle. Therefore, we should prohibit the clogging of materials in the machine, and clean up the clogging in time.
