Vibratory Screening and Dewatering

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.  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.

Frac Sand Screening Equipment


Derrick® Stack Sizer®

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.

  • Process up to 150 tons per hour per Stack Sizer
  • Low operating cost
  • Low horsepower (5HP total) for each Stack Sizer
  • Polyweb® urethane screen surfaces typically last 8-10 months or longer thus reducing employee exposure to silica dust
  • Minimal dynamic loading for support structure
  • Rubber and urethane lined hoppers and feed boxes for long life
  • U100 urethane coating sprayed on vibrating screen frame to protect against abrasive sand

Derrick® Fines Recovery System

Dewater and recover fines from aggregate and sand processing wastewater WITHOUT the use of expensive polymers or chemicals. With many installations throughout North America, the Derrick® Fines Recovery System is proven successful in the field and continues to lead the way for the aggregate industry.

Applications include:

  • Drying and cleaning aggregate – dewatering, desliming, degritting and rinsing
  • Sand and sand slurry processing and separation – replacement of sand screws
  • Solids recovery from dirty water or wastewater
  • Reduction of settling pond sedimentation
  • Dewatering of solids from dredging operations
  • Frac sand processing and recovery free of clays


  • Features & Benefits

  • Recover up to 80% of the silts and ultra-fine sands that are currently flowing to your settling ponds
  • Drastically reduce pond cleaning and maintenance costs and extend the life of settling pond facility
  • Reduce settling pond size
  • Enhance water quality back to aggregate and sand processing or for public discharge
  • Satisfy safety and environmental issues associated with pond use
  • Turn wasted material into a marketable product
  • Requires NO expensive polymers or chemicals

Urethane Screen Panels

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.

Wet Screening & Dewatering Equipment

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.

Dry Screening Equipment

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.



Front-to-Back™ Dry Screening Machine

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).

  • Features & Benefits

  • Rotating the screen panel tensioning 90 degrees positions the crown of the screen parallel to the material flow assuring an even distribution of material across the entire width of the screen
  • Increased capacity
  • Reduction in screen panel wear increasing the life of the screen
  • Elimination of blinding
  • Change a screen panel in 4 simple steps
