It is important to know that the shape of the sand has an important impact on the surface finish of the casting. Circular sand is better than triangular sand because the triangular sand has a large gap, which is easy to lead to defects such as porosity; According to the nature of the casting, the sodium silicate quartz sand is selected to form a spalling layer, and combined with the characteristics of cooling and shrinkage of the casting, the surface defects are reduced. Coating a protective layer on the surface of large castings, such as the film on a coated sand mold, can improve the surface finish of the sand mold and reduce the surface defects of the casting.

One of the most critical components of a jaw crusher is the jaw plates. These are the surfaces that come into direct contact with the material being crushed. They typically come in two varieties the fixed jaw plate and the movable jaw plate. The fixed jaw plate is stationary and mounted on the frame, while the movable jaw plate moves back and forth, creating a crushing motion. The wear and tear of jaw plates are significant since they constantly encounter abrasive materials. Hence, they are often manufactured from high-grade manganese steel to enhance their durability.
