Uncontrolled dry processing of materials containing crystalline silica is prohibited. This means silica dust must be captured or suppressed (usually with water) when cutting, grinding, sanding, polishing, drilling and mixing materials containing crystalline silica. Stop or reduce the amount of silica dust being produced Some methods include:
Silica Sand is quartz that over time, through the work of water and wind, has been broken down into tiny granules.. Commercial Silica Sand is widely used as a proppant by companies involved in oil and natural gas recovery in conventional and unconventional resource plays. The resource is also used in industrial processing to make everyday items such as glass, construction .

Properties of Molding Material Dry Strength ` It is the strength of the molding sand in dry conditions. ` When the molten metal is poured in the mold, the sand around the mold cavity is quickly converted into dry sand as the moisture in the sand evaporates due to the heat of the molten metal. ` At this stage the molding sand must posses the sufficient strength to retain the .
