How to improve the service life of the jaw plate of the jaw broken and vulnerable parts?
May 17, 2022
The main wearing parts of jaw crusher are side plate, movable jaw plate, fixed jaw plate, and the material choice of jaw plate is generally high manganese steel, high manganese steel as jaw plate has good impact load resistance, so it is widely used, so why is high manganese steel especially preferred? How to operate to prolong its service life?
When the harder material enters the jaw, it constantly impacts the jaw plate, so that it reaches the phase change degree, so that the surface tissue is hardened, the impact of the internal soft and external hardened jaw plate increases, and the wear-resisting degree also increases, and the service life is greatly improved after the jaw plate is hardened.
But on the contrary, the soft material enters the jaw after breaking the impact strength is not enough, the jaw plate can not reach the phase change degree has been worn, it will increase the purchase cost of wear resistant parts.
