Smarter Sand Washing
Cyclones, Dewatering Screens, & Screw Washers That Work Harder For You.
Still Losing Sand to Your Pond?
Every day, producers across B.C. are watching fine sand and profits slip away with their wastewater.
Whether you’re running a gravel pit, recycling Hydrovac spoils, or prepping material for construction use, there’s one truth you can’t escape: clean, well-classified sand sells and muddy, oversized piles don’t.
Why Sand Washing and Classifying Matter
When it comes to aggregate production, it’s not just about how much material you process, it’s about how much value you recover. Unwashed material is full of clay, silt, organics, and ultra-fines that downgrade your final product and jam up your equipment. If you’re not washing and classifying properly, you’re:
Hauling and stockpiling more than you need
Paying to dispose of sellable material
Missing out on premium sand markets
The right wash plant can cut your waste, improve product quality, and open new revenue streams—with less water, less downtime, and fewer headaches.
Reduce Waste
Recover more usable sand and keep it out of the pond. Smarter classification means less product lost; less cleanup.
Boost Profits
More yield, drier sand, fewer hours lost to rehandling—this is how you make every ton count.
Protect Equipment
Cleaner discharge reduces wear and tear on stackers, bearings, and belts—helping your machines last longer.
Choose the Right Wash System for Your Operation
There’s no one-size-fits-all. That’s why we carry the full range, from traditional sand screws to modern cyclone-based systems with dewatering screens. Here’s how they compare:
Cyclone + Dewatering Screen
Maximum recovery. Minimal moisture.
Uses centrifugal force to separate valuable sand from water and ultra-fines
Fine material stays in your stockpile—not your pond
Produces drip-free sand at just 14–15% moisture
Low maintenance—no augers, no gearbox, no constant shoe replacement
Perfect for: High-production operations, tight pond space, and producers who want to keep their fines, not flush them.
Wet Screen / Sand Screw Washers
Reliable but limited.
Uses a slow-turning auger to lift sand out of a slurry tub
Struggles to recover finer sand sizes
Produces wetter product with messy discharge
Higher maintenance—frequent wear part replacement and more downtime
Best for: Simpler applications where yield loss and water use aren’t a concern.
Let’s Get Technical
When choosing between a cyclone system and a screw washer, here’s what you need to know:
| Feature | Cyclone + Dewatering Screen | Screw Washer |
|---|---|---|
| Sand Recovery | High (100–200 mesh) | More Usable Fines Lost |
| Moisture Content | 14–15% | 20%+ |
| Maintenance | Minimal | Moderate |
| Water Use* | Heavy | Moderate |
| Wear Parts | Low | Frequent |
*Water Use vs Water Recovery It’s true, cyclone classifiers combined with dewatering screens use more water than traditional sand screws. But they make up for it by recovering significantly more fines, delivering a much drier, more salable product, and, depending on the setup, often support greater water recycling. In the long run, you’re getting more product and better water management, which means a stronger return on investment.
Upgrade Your Wash Plant
Your sand deserves better than the bottom of the pond.

The Terex® T 150 is a mobile bucket wheel dewaterer complete with a fines retention screw and twin bucket wheel designed units for removing clays, silts and slimes to produce up to 2 grades of sand.
The T 150 is designed to operate with maximum versatility and can support different requirements such as maximum retention of fines or maximum disposal of fines.
The T 150 can be driven hydraulically from the M Range or its own optional electric power pack.
Dewatering Screens
Built to Perform in Demanding Conditions
Terex dewatering screens are engineered with rugged construction to handle a wide variety of applications. While they are primarily used for dewatering and retaining fines, their versatile design allows them to perform effectively across multiple material processing scenarios.
The screen features a 45° sloped back deck with slotted apertures positioned across the flow direction to optimize drainage. The main deck slopes upward at 5°, and efficient vibration is delivered by two exciter motors operating at 980 RPM—ensuring consistent, high-performance output.
