Drain as much water as possible out of your aggregate materials with this line-up of dewatering screens and screws.

Dewatering screens increase production while removing water.

Linatex

The G4 dewatering screen from Linatex features a curved, sieve-like feed section and upward-inclined main deck for increased dewatering. The company says the use of centrifugal force allows a larger total screening area without increasing the size of the machine.

Derrick Corp.

Derrick Corp. says its new W56 dewatering screen features true-High G force linear motion coupled with a high-open-area urethane screen surface to allow water removal at up to 300 tons per hour. The unit is operated by two vibratory drives and can be outfitted with spray bars for a cleaner end product.

GreyStone

GreyStone, Inc. offers three dewatering screen models — the 4- by 8-foot DS-488, the 5- by 10-foot DS-6010, and the 6- by 12-foot DS-7212. The units produce a dense, compact cake that rides up the belt to form a pile with no runoff or water pools. The high-frequency separators have an adjustable bed depth, table tilt, and vibrator variables.

Metso

Metso Mining & Construction says the first section of its high-capacity dewatering screen is constructed with a sharp 45-degree slope to remove water during the initial screening process. The remaining reverse-incline sections retain material and compact particles into a “filter cake” where most of the remaining moisture is removed.

Sizetec

The reverse-angle deck, VDS dewater screens from Sizetec, Inc. are available in many sizes — 2 by 7 feet, 3 by 8 feet, 3 by 10 feet, 4 by 10 feet, 5 by 12 feet, 6 by 12 feet, and 7 by 14 feet. All screens are equipped with either 1,200- or 1,800-rpm motors; the largest screen can dewater sand at up to 300 tons per hour.
