Cone crusher is widely used in metallurgy, construction, mining and other industries. It can be used as secondary crushing or tertiary and quaternary crushing. Various vulnerable parts of hydraulic cone crusher, composite cone crusher and spring cone crusher are collectively referred to as cone crusher accessories. The structure of cone crusher is mainly composed of frame, horizontal shaft, moving cone, balance wheel, eccentric sleeve, upper rolling mortar wall (fixed cone liner), lower crushing wall (moving cone liner), hydraulic coupling, lubrication system, hydraulic system, control system, etc. among them, crushing wall rolling mortar wall is the most common wear-resistant accessory.

Using high-quality raw materials, through scientific and reasonable element ratio (molybdenum, manganese, rare earth lanthanum, etc.), one-time forming after smelting in medium frequency furnace, and then after a series of heat treatment processes (heat treatment temperature reaches 1045 ℃), the toughness and wear resistance of the products have achieved good application results.
