The crushing mechanism of the mobile jaw crusher plant: the mobile jaw crusher plant crushes the material through the squeezing movement of the movable jaw relative to the fixed jaw, so the wear of the jaw plate during use is quite serious. So, what are the treatment methods for the wear of the jaw plate of the jaw crusher? The following is a detailed introduction to you from five aspects.

1. Equipment parameter shall be compatible with materials

Sampling each batch of materials and when discovering that there is a large fluctuation in the nature of the materials, users should timely adjust the main parameters of the crusher, such as clamp angle, eccentric shaft speed, output and motor power, etc. To adapt to reduce the wear of the jaw plate.

2. Pay attention to tightening the jaws

Pay attention to the tightening of the newly installed jaw plate, and ensure that the surface of the jaw plate and the body (moving and static jaw) are in stable contact. Lead plates, plywood cement mortar and other plastic materials can be cushioned between the two surfaces. The assembly requirement for the movable jaw plate and the static jaw plate is that the tooth peak of the jaw plate is aligned with the tooth groove of the other jaw plate, that is, the movable jaw plate and the fixed jaw plate are in a basic meshing state.

3. Material selection of jaw plate

The jaw plate should be made of materials with high hardness to resist the failure of extrusion micro-cutting. Choose materials with sufficient toughness to resist fatigue failure caused by chiseling impact. Usually high manganese steel containing 12% to 14% manganese is used to cast the jaw plate. The small jaw crusher can also use white cast iron to make the jaw plate, and to improve the structure of the tooth plate to reduce the relative sliding of the material and the tooth plate. Because the jaw plate is usually made into a symmetrical shape, it can be used upside down when the jaw plate has been worn down during minor repairs. The jaw plate of the large jaw crusher produced by CFTC is composed of several pieces, which can be used interchangeably to extend the service life of the jaw plate.

4. Interchange the same type jaw plate

Cement enterprises with a mine crushing process line can exchange the same type of worn jaw plats in the coarse crushing of the mine and the fine crushing of the cement plant to replace the new jaws and continue to serve.

5. Adopting surfacing welding or arc welding

For the jaw plate that has worn out and failed, the method of surfacing welding can be used to restore the tooth shape. Electric arc welding or automatic submerged arc welding can be used for repair.
