Wet screening sand and aggregate High-capacity wet and dry screening using panels that are constructed from a special high temperature polyurethane material. Vibratory screening equipment is used to screen or classify wet or dry materials, like wet ash or dry frac sand, into multiple grades by particle size.
The hole size of the sand screen will dictate the size of sand particles blocked or permitted into the bore. You should select a sand screen with the correct hole size to balance the production and sand collection. If the screens have huge holes, a large quantity of sand will enter the bore leading to sand plugging.
