AZFAB says its dewatering screens, designed to replace or enhance sand screws, use 1-foot by 1-foot urethane modules to produce an average moisture content of only 12 to 14 percent, depending on particle and tonnage size. In some cases, moisture content is as low as 7 percent. The 5-foot screen is capable of processing up to 150 tons per hour; the 7-foot screen is rated at 300 tons per hour. Custom sizes are available.

Derrick says its W-series dewatering screen uses a unique, high-open-area urethane screen surface coupled with the high G force of the vibrator to provide high-tonnage-rate dewatering, reaching 95-percent solids by weight for primary sand products. The screen features low horsepower and low footprint requirements.

EIW, LLC, formerly known as Eagle Iron Works, offers single- and double-screw units for washing, dewatering, and classification. Material is conveyed up an inclined tub with a close-clearance curved plate on one side of the conveyor shaft and a drainage trough on the other. This allows water to drain from the product as the spiraled shaft augers material up the inclined curved plate.

The GreyStone Aggre-Dry is a combination fine material washing screw and dewatering screen in a single unit. The company says its compact design creates two benefits: 1) water is recirculated back into the water retention system, reducing water going to the stockpile by 50 percent; and 2) fines that get through the screen media are recycled back into the screw.

KPI-JCI says its Kolberg 9000 Series dewatering screen is capable of reducing moisture content of washed sand down to as low as 8 to 15 percent. It is available in multiple sizes ranging from 2 feet by 7 feet up to 8 feet by 16 feet. The screen’s 1/4-inch stroke operates at 1,200 rpm, providing high G-force action. It is equipped with urethane media; has an adjustable incline from 0 to 5 degrees; and can be packaged in portable, semi-portable, and stationary systems.

McLanahan says its dewatering screen has one of the highest capacities in the industry, processing up to 400 short tons per hour on a single machine. It features heavy side plates and stress-relieved bridges and cross beams. The company says its rugged, easily maintained design is the key to long-term performance and flexibility.
