The crushing principle of the jaw crusher: relies on the crushing movement of the moving jaw relative to the fixed jaw to crush the material, so the wear of the jaw in the process is quite serious. Then, what are the treatment methods for jaw crushing of jaw crusher? The following is a detailed introduction to you from five aspects.
1. Equipment parameters are adapted to the materials
Sampling each batch of materials, and found that the material properties have a large fluctuation, timely adjust the main parameters of the crusher, such as the clamp angle, eccentric shaft speed, output and motor power, etc., and make it into the crusher material Adapt to reduce the wear of the seesaw.
2. Pay attention to fastening the board
The new fascia should be fastened and the surface of the slab should be in smooth contact with the surface of the body (moving and static). A plastic material such as a lead plate or a plywood cement mortar can be placed between the two surfaces. The assembly requirement for the movable jaw and the static slab is that the chirp of the raft is aligned with the gullet of the other raft, that is, the movable raft is in a substantially engaged state with the fixed raft.
3. Eb material selection
The slab should be made of a material with high hardness to resist the failure of extrusion micromachining. A material with sufficient toughness is used to resist the fatigue failure caused by the chiseling impact. Usually, high manganese steel containing 12% to 14% manganese is cast into a slab. The small jaw crusher can also be used to make the jaws from white cast iron, while improving the tooth plate structure to reduce the relative sliding of the material and the tooth plate. Since the jaws are usually formed in a vertically symmetrical shape, the lower worn jaws can be inverted for use during minor repairs.
4. Interchange the same type of board
A cement enterprise with a mine crushing process line can replace the same type of wear and slabs that are crushed in the mine and crushed in the cement plant, and replace the new raft to continue to function.
5. Using surfacing or arc welding
For the seesaw that has worn out, the surfacing method can be used to restore the tooth shape. Arc welding can be used for repair, or automatic submerged arc welding can be used.
