The vulnerable parts of jaw crusher mainly include side guard plate, movable tooth plate, fixed tooth plate, elbow plate and spring. The material of jaw plate is generally high manganese steel. High manganese steel, as the jaw plate of jaw crusher, has good impact load resistance, so it is widely used. So why is high manganese steel particularly preferred? How to make it prolong its service life?

When hard materials enter the jaw crusher, they constantly impact the jaw plate to make it reach the degree of phase transformation, so as to harden the surface, and increase the impact and wear resistance of the jaw plate after internal soft and external hardening, and greatly improve the service life after the jaw plate is hardened. However, on the contrary, the impact strength of soft materials after entering the jaw crusher is not enough, and the jaw plate has been worn before reaching the phase transformation degree, which will increase the procurement cost of wear-resistant parts.

So if you want to improve the service life of the jaw crusher’s jaw plate, you can crush the hard materials firstly. Just leave messages for more help if there is any question!
