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. They are also used to dewater or dry waste material before disposal. This type of high frequency vibrating equipment only drives the rectangular polyurethane screen panel, while the frame remains fixed. High capacity screening equipment can screen or classify material ranging in sizes from 1/8 inch (3mm) down to 325 mesh.

The Derrick Stack Sizer is a high capacity, multiple deck, wet screening machine capable of high capacity wet screening in a small footprint. A single slurry input is equally divided in a Derrick flow divider prior to the Stack Sizer. Each screening deck then makes a particle size separation on the Derrick Polyweb Urethane screen surfaces. The undersized fraction is collected from all decks in a common manifold to a single discharge. The oversize fraction is collected in the large hopper and discharged to a common point.

Derrick MP screen panels are constructed from a special high temperature polyurethane material. They are a direct replacement for the traditional wire mesh panels currently used in the Rotex MegaTex screeners. These panels have a tapered opening to greatly reduce blinding issues commonly experienced with wire mesh panels. Because of the reduced blinding, the screen production rate can be increased over wire mesh panels. Typical life span is greater than 6 months. Urethane screen panel sizes are available for typical frac sand production.

High capacity wet screening and dewatering equipment provides a wide range of sizing and classification tasks. Wet screening equipment efficiently screens out fines and classifies oversize particles. Dewatering units have proven throughput of up to 300 TPH (tons per hour) and are designed to maximize solids recovery and minimize wastewater.

The dry screening equipment featured below use high speed, low amplitude, and vertical elliptical motion to screen dry materials such as sand, iron powder, nickel powder, polyethylene pellets, coal, glass, and many other materials. These machines produce low amounts of sound and are fully enclosed for dust suppression. Light-weight screen panels and hinged and clamped covers provide easy screen inspection, removal, and installation.
The Front-to-Back (FTB) dry screening machine provides increased screening capacity, improved efficiency, and extremely fast screen panel changes. Customers using the FTB machine report screening capacity increases up to 50% with improved efficiencies in products ranging in size from 0.25 inch (6.35mm) down to 400 mesh (38 µm).
