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.

Mining slurry pumps are designed to handle abrasive materials, including gravel, sand, and other particulates mixed with water. Their construction typically features robust materials like high-chrome alloys or rubber linings designed to withstand harsh conditions and minimize wear. The pumps are specifically engineered to handle high solid content and varying densities, making them indispensable in mining applications.
