Shape comparison between natural sand proppants and ceramic proppants. There are two clearly different ranges of Aspect Ratio ( Krumbein's Sphericity ). Analysis of other shape parameters are possible as well (Convexity for ceramic bead

Prohibit silica sand (or other substances containing more than 1% crystalline silica) as an abrasive blasting material and substitute less hazardous materials. Conduct air monitoring to measure worker exposures. Use containment methods such as blastcleaning machines and cabinets to control the hazard and protect adjacent workers from exposure.

Silica Sand Silica sand is essentially the primary material used in glassmaking, blended together with fluxes, firing agents, stabilisers, colourants and other components for efficient melting and forming processes, as well as the desired product characteristics.

The production of these specialist silica sands for application in glass manufacturing requires specialist screening and classification equipment from CDE. This complex process will first involve a detailed analysis of your feed material both in terms of the particle size distribution (PSD) and the chemical properties of your silica sand.
