GreyStone dewatering screens allow producers to sell material faster by eliminating waiting periods for stockpile drying. Many concrete and masonry sands typically retain from 18 to 24 percent moisture, which generally requires between one-to-two weeks of drying time before it can be sold. At the end of your operation, GreyStone Dewatering Screens can receive a high percentage of water-saturated fine material and produce a dense, compact cake that rides up the belt and forms a pile with no runoff or water pools. The end result is a dry, transportable product—with a moisture content as low as 8 percent—that can be sold in less than a day.  | GreyStone Dewatering Screens produce saleable material with a moisture content as low as 8 percent. |
GreyStone offers three models that handle a variety of capacities—DS-488, DS-6010 and DS-7212—to efficiently dewater up to 350 tons per hour. GreyStone’s Dewatering Screens are constructed of high-quality ASTM A36 structural steel for years of trouble-free service life. Features and Benefits of GreyStone Dewatering Screens
• Adapts to each plant’s unique material by combining the adjustable motor force in conjunction with
the adjustable bed tilt. Once setup is achieved with favorable steady-state conditions, operation starts with a
simple flip of a switch.
• The sand stockpile produced stacks high and nearly dry, without forming water pools at the base of the
equipment. Eliminating water runoff from material stockpiles helps producers answer local environmental
concerns.
• A high-frequency separator allows producers to easily adjust bed depth, table tilt and vibrator variables to
remove up to 50 percent of the water, while maintaining maximum production no matter how wet the material is.
Two vibrators initiate a linear motion, driving particles in an uphill, downhill or horizontal direction—so water is
strained down through the sand bed and below the screen deck.
• A urethane deck with a 1/4-mm aperture allows the user to dewater a broad range of particle sizes. The deck
can handle up to 14 inches of material depth, making use of the bottom thin layer of material as a secondary
“screen,” allowing the deck to preserve fines smaller than 200 mesh.
• A +/- 5-degree bed angle tilt allows producer to better adapt to material volume, gradation and water retention
changes and create the proper material bed depth. With GreyStone’s 30 different classifier configurations and the ability to supply all your washing, classifying and dewatering equipment needs, they can custom-design a complete operation to meet your specific application and production requirements. You can send them a sample of your pit run material for a free sieve analysis and recommendation.
