Artificial Sand Making Process Raw Materials. The manufacturing of the Sand process involves three stages. These are crushing of stones in to aggregates by VSI, then fed to Rotopactor to crush aggregates into the sand to required grain sizes (as fines). Then, do the screening to eliminate dust particles and Washing of sand eliminates very fine particles present within. Finally, the end product will satisfy all.
Silica, otherwise known as industrial sand, provides the most important ingredient for glass production. Silica sand provides the essential Silicon Dioxide (SiO2) required for glass formulation, which makes silica the primary component in all types of standard and specialty glass.

If the shear strength of the sand is below that of the pressure created by the liquid metal filling the mold, the core might split and create a distortion in the casting body. Binders are a big part of the core-sand making process. Green sand cores are made from standard damp molding-sand mixtures, and a binder, like dextrin. Cores of this type.
