silica sand wet scalping screen

Three vibratory screens are being use to scalp oversized silica sand particles in wet screening application. Sand and water is being fed from a water separator onto the screen surface. All sand particles larger than 40 mesh are scalped off and removed from the flow.

A Frac Sand Producer was looking to increase production rates at an existing production plant. The product specification goal was to produce a consistent 40 X 70 API (American Petroleum Institute) standard product.  Feed to the Stack Sizer screening machines is from a processed material stream that discharges from a hydrocyclone at a solid feed rate of 150 stph.
