In the production process of castings for crusher wear parts, both mechanical sand adhesion and chemical sand adhesion pose significant challenges affecting product quality. The pores on the surfaces of molds and cores tend to allow molten metal to seep in during casting, resulting in stubborn mechanical sand adhesion that is difficult to remove. By applying a specialized coating to the surface of crusher wear part castings, these pores can be effectively sealed, blocking the pathways for molten metal penetration and significantly improving the surface finish of the castings.

How do the moving and fixed jaw plates work together to crush materials?
The jaw crusher, a critical piece of equipment in the coarse crushing stage of material processing, is widely used in industries such as mining and construction. Its core working principle relies on the coordinated action of a moving jaw plate (also known as the movable jaw liner) and a fixed jaw plate (the stationary jaw liner), which crushes materials by squeezing them within a V-shaped crushing chamber formed by the two high-manganese steel jaw plates.
