How to choose the liner of the jaw crusher

Choosing the appropriate cavity shape of the jaw crusher is not simple and there are no rules. Because each application has many different variables, such as ore type, feed port, product requirements and problems, etc.

It is true that some liner cavity shapes will reduce or increase the hourly output of the crusher. Therefore, it is necessary to be proficient in the crushing operation and observe the conditions in the crushing cavity (layered materials, excessive humidity, powder materials, small discharge port requirements, etc.). What can we do for the liner of the jaw crusher?　　

When the liner of the jaw crusher is severely worn, the of the crusher is not , which is a well-known fact. Because the space between the teeth of the jaw crusher is reduced, the teeth frequently bite, and the crushing angle changes; or in other words, the output is affected. The cost-benefit analysis of the replacement of the liner of the worn jaw crusher should be carefully performed. In a sense, the decline in output fully proved the need to replace the liner of a new jaw crusher.

Under the condition of uniform wear of the jaw crusher's lining plate, all the manganese steel teeth are fully utilized, without turning over the jaw plate lining plate or adjusting production. However, this is impossible. Due to the broken movement pattern, it is inevitable that certain areas will be severely worn, such as the lower part of the fixed jaw liner and the middle of the movable jaw liner. Therefore, the liner of the jaw crusher should be turned over once to make better use of the liner . However, we recommend turning over twice, that is: fixed jaw liner-when the wear of the lower area reaches about 50%, implement the * (up and down) turnover; when the wear of the new lower area reaches 90%-100%, perform Flip for the second time. After the second time, the remaining 50% wear life of this end was consumed. Movable jaw liner-the same procedure is also applicable, although wear occurs in the middle area of ​​the liner, it rarely occurs in the middle.
