Evaluate the Quality of Jaw Crusher

The working mechanism, which is crushing cavity, of jaw crusher is formed by a fixed jaw and a mobile jaw. On both jaw plates, there are lining boards made of manganese steel and they are fixed onto the jaw plate with bolts and wedge. As lining boards directly participate in the crushing process, to improve the crushing effect, on the surface of the lining boards, there are horizontal ripples which are set opposite each other in lumps and bumps. At present, the tooth form of jaw crusher is triangle or trapezoid on which there are vertical bars. With the application and development of computer technology, the design of tooth form has developed from traditional test method and experience method to applying computer for optimized design, thus gaining optimum crushing effect.

Jaw crusher is one of the frequently used crushing equipment. When dealing with coarse crushing and medium crushing, jaw crusher comes in handy instead of impact crusher, cone crusher and sand making machine, etc. On the one hand, jaw crusher has a simple structure and is easy to maintain. On the other hand, jaw crusher in inexpensive. Since jaw rusher is so significant, which kind of jaw crusher is the best? Three ways to estimate jaw crusher’s quality are as follows.

First, look at the rust-removal quality of the welding assembly. As an iron-made crusher, rust-removal quality of the welding assembly influences jaw crusher’s running life directly. To achieve this goal, sample plates comparison and visual examination ways are mostly used.

Second, the important aspect is to check the texture of jaw crusher’s main parts. About this, we can turn to physical and chemistry experimental proof or relevant texture certification.

Third, measure jaw crusher’s opening discharge width. When measured, the jaw crusher must be placed steadily, then measure it by caliper or steel ruler. Without the function of mining machine, the economy will not advance and make progresses.
