Simple maintenance method for jaw crusher
« on: July 08, 2019, 10:32:31 AM »

Jaw Crusher is the basic crushing equipment in the mining equipment produced by Zhengzhou crusher manufacturers. It is also the mainstream sand making equipment with the largest sales volume and the highest production efficiency in the mining equipment industry.
The jaw plate of the Jaw crusher is a part that is in direct contact with the material. The wear is the fastest, and the service life is also short. It is usually 1~3 months, and some even need to be replaced only 1~2 weeks. Therefore, the user needs to be proficient in the repair method of the jaw crusher jaw plate to extend the service life of the jaw crusher and reduce the investment cost. Let the technical staff of the crusher manufacturer explain the specific repair method.
Zhengzhou crusher manufacturer tells you about the repair method of the Jaw crusher jaw plate
1. Lead-containing surface of the welded part is ground with a grinding wheel by 2~3mm.
2. When welding, try to avoid the parent body being heated too much, and hammering the welding after welding to eliminate the internal stress of the welding.
3. The order of surfacing is to first weld one layer on all the teeth on the tooth plate, and then weld the second layer, instead of welding all the surfacing layers of one tooth first, then welding one tooth. Avoid welding deformation of the mother body that is too hot or too large. The speed of surfacing should be fast, the lateral oscillation should be small, try to use small-diameter welding rod and small welding current, and the cooling speed after welding should be fast. When conditions are met, the high-manganese steel casting can be placed in water, and only the surfacing part is exposed. If conditions permit, it is best to carry out quenching heat treatment after welding.
