Next Generation Sand Screw
The Aggredry Dewatering Washer, a combination wet screw and dewatering screen, can be used anywhere a fine material washer might be used. However, the added benefits pay back your investment in a very short time.
Generally speaking, traditional sand screws produce material with a moisture content of about 15-20%. That sloppy sand can be impossible to run up a stacker, takes weeks to dry and wears on other equipment. Meanwhile, the precious water is wasted as it usually evaporates before finding your pond.
While material moves through an Aggredry Washer’s screw section clays, dirts and fines are separated before the good sand moves to an attached dewatering screen.
The major disadvantage of dewatering screens has always been lost material, but that’s the superpower of this machine. Those lost fines collect in an underflume and are flushed back to the screw. This patented jet is constantly reclaiming and returning valuable material.
Sand discharges from the Aggredry Washer with a moisture content as low as 8% and is instantly available for sale or further processing.
- Single or twin screw options
- Capacities up to 800 STPH (725 MTPH)

How much better could you do with an Aggredry Washer?
Features & Benefits
Fine material washer
Single or twin screw models accept feed sizes up to 3/4” (19mm). Separates unwanted slime and dirt from sand.
fines recovery jet
Valuable ultrafines that collect below the screen are flushed back to the screw.
Deeper bed depth combined with sidewall media produces a drier product.
Safeguard™ outboard bearing
Off-the-shelf pillow block bearing installed outside the tank to shield from moisture.
Curved shape eliminates dead spots for material to gather, which is common at 90° angles.
5 Disadvantages of Wet Sand
Do you use a fine screw in your application without a drying or dewatering stage? Sand processed through standard screws retains about 25% moisture, which affects performance throughout the rest of your plant.
Five disadvantages of wet sand:
- Extra real estate required for drying stockpiles
- Reduced lifespan of rolling stock tires
- Water run-off makes for a messy operation
- Sand sticks to conveyor idlers and pulleys
- Wasted water evaporates before reaching pond
