Frequently Asked Questions

It can wash river sand, manufactured sand, quartz sand, silica sand, feldspar sand, crushed sand and selected fine aggregate. The feed should remain within the specified size, and suitability should be confirmed from clay content, abrasiveness and required product grading.

Choose a spiral sand washer when the process requires active agitation, washing, desliming and upward conveying in one machine. It is often considered for material with more silt or surface contamination than a wheel washer can efficiently handle. Highly plastic clay lumps may require stronger scrubbing equipment or material testing.

Water consumption depends on the model, feed rate, clay content, feed moisture, overflow setting and required product cleanliness. Water demand should be calculated from the actual process rather than using one fixed value for every model. A settling and recycling system can reduce fresh-water demand.

Some fine particles can leave with the overflow water. The amount depends on feed gradation, water flow, pool level and operating settings. If valuable fines must be retained, connect the overflow to a hydrocyclone or fine-sand recovery system.

A single-spiral machine uses one shaft and is generally selected for lower or medium capacities. A double-spiral model uses two parallel shafts and provides greater conveying and washing capacity. The increase is not always exactly double because capacity also depends on spiral diameter, trough length, feed conditions and motor configuration.

Yes. XINGAONAI supplies new single- and double-screw sand washers for aggregate and manufactured-sand plants. Model selection is based on feed size, required capacity, clay content, product grading and water conditions.
