Sand washing equipment removes silt, clay and stone dust from manufactured sand and natural river sand before the material reaches a concrete batching plant. Baichy builds two families for that duty: the XSD bucket wheel washer, which handles 20-300 t/h of feed sized 10 mm and below, and the XL screw washer, which accepts feed up to 30 mm at 40-280 t/h in single- or double-spiral versions.
Which Sand Washing Machine Fits Your Material?
Clay content decides the type. A bucket wheel washer loses less than 3% of fine sand and suits river sand carrying 3-8% mud; a screw washer suits feed carrying 15-20% clay and cuts it to below 0.8%.
• River sand with 3-8% mud — the XSD bucket wheel washer lifts washed sand out of the tank and drops it into the discharge chute, while the overflow port carries the mud away.
• Sea sand with salt and shell fragments — two bucket wheel washers in series, the first for the coarse wash, the second for the rinse.
• Weathered rock and clay-rich manufactured sand — the XL screw washer in double-spiral form, 2XL1120-7.5 or 2XL1500-9, where the second spiral doubles sink length from 5000 mm to 10000 mm and from 9800 mm to 18000 mm.
• Water-scarce sites — the XL trough discharges silt over its weir plates, and behind a sedimentation tank more than 80% of the process water returns to the circuit.
• Quartz, silica sand and iron ore tailings — desliming and classification, where the silt and the fines have to come out before the material moves to the next processing stage.
Wheel Sand Washer (XSD Series) Specifications
Wheel-bucket sand washer
An XSD bucket wheel turns slowly inside a water tank, driven by a motor through a V-belt and a gear reducer. Grains rubbed against one another shed the mud and stone dust that cling to their surfaces, and the overflow port takes those impurities out of the tank.
| Model | Impeller Dia. (mm) | Feeding Size (mm) | Capacity (t/h) | Motor Power (kW) |
|---|---|---|---|---|
| XSD2300 | Φ2300 | ≤10 | 20–30 | 4 |
| XSD2610 | Φ2600 | ≤10 | 30–80 | 7.5 |
| XSD2915 | Φ2900 | ≤10 | 60–120 | 11 |
| XSD3016 | Φ3000 | ≤10 | 80–160 | 15 |
| XSD3218 | Φ3200 | ≤10 | 130–220 | 22 |
| XSD3420 | Φ3400 | ≤10 | 160–300 | 22–30 |
Feeding size is published as one value for the whole XSD range. In a manufactured sand line the same tank takes stone powder from 10-20% down to 3-5%, and impeller diameter grows from Φ2300 mm on XSD2300 to Φ3400 mm on XSD3420.
Spiral Sand Washer (XL Series) Specifications

The XL trough is set at 15°, and the screw shaft turns at 8-18 r/min. Clean sand settles to the bottom of the tank, the blades push it up the incline, and silt leaves over three overflow weir plates while fresh water enters through a perforated pipe at the tank floor.
| Model | Spirals Number (pcs) | Screw Diameter (mm) | Sink Length (mm) | Capacity (t/h) | Motor Power (kW) |
|---|---|---|---|---|---|
| XL920-7.5 | 1 | ∅920 | 3600 | 40–60 | 4P-11 |
| 2XL920-7.5 | 2 | ∅920 | 7500 | 90–120 | 4P-11×2 |
| XL1120-7.5 | 1 | ∅1120 | 5000 | 40–120 | 4P-18.5 |
| 2XL1120-7.5 | 2 | ∅1120 | 10000 | 80–240 | 4P-18.5×2 |
| XL1500-9 | 1 | ∅1500 | 9800 | 100–170 | 4P-22 |
| 2XL1500-9 | 2 | ∅1500 | 18000 | 200–280 | 4P-22×2 |
Sand leaves the trough at 12-18% moisture, low enough to stockpile or to load straight onto a belt conveyor without a second dewatering step.
Bucket Wheel Washer vs Screw Washer: Which Fits Which Job?
The two types separate on feed size and on fines retention. A bucket wheel washer stops at 10 mm feed and loses under 3% of fine sand, while a screw washer takes 30 mm feed and uses 60-70% of the power per ton.

How Do You Size a Washer for a 100 t/h Sand Plant?
A 100 t/h washed-sand duty is covered by XSD3016 at 80-160 t/h with a 15 kW motor or by XL1500-9 at 100-170 t/h with a 22 kW motor; feed size and clay content decide between them.
Check feed size first — a bucket wheel washer accepts 10 mm, a screw washer accepts 30 mm.
Then match the tonnage — one spiral on XL1500-9 covers 100-170 t/h, two spirals on 2XL1120-7.5 cover 80-240 t/h.
Recover the fines — add a fine sand recovery machine downstream when the washed sand feeds a concrete plant with a tight fines specification.
FAQ: Sand Washing Equipment
What is the difference between a wheel sand washer and a spiral sand washer?
A bucket wheel washer turns a bucket wheel in a water tank and holds fine sand loss under 3%; a screw washer uses a 15° inclined screw at 8-18 r/min and cuts 15-20% clay to below 0.8%. Take the bucket wheel for low-clay natural sand, the screw washer for clay-rich feed up to 30 mm.
How much fine sand does an XSD bucket wheel washer lose?
Less than 3% of fine sand, which is why the XSD series is used on natural river sand whose grading has to be preserved. In manufactured sand the same tank takes stone powder from 10-20% down to 3-5%.
Can a bucket wheel washer desalinate sea sand?
Yes, with two XSD units in series: the first performs the coarse wash that removes salt and shell fragments, and the second rinses the sand before it goes to the stockpile.
What is the maximum feed size of an XL screw washer?
30 mm, three times the 10 mm limit of the XSD bucket wheel. That tolerance is why the screw type is specified for weathered rock and for ore desliming duty.
Which model suits a 100 t/h sand washing plant?
XSD3016, rated 80-160 t/h on a 15 kW motor, or XL1500-9, rated 100-170 t/h on a 22 kW motor. Choose on clay content and feed size rather than on capacity alone.
