Dewatering bucket wheels are used for sand extraction and enrichment.
Dewatering bucket wheels with lateral spirals are developed for fine sand extraction.
Water-sand mixture is transported to the wheel and the larger segment of solid substance is taken by the wheel and transported by the buckets. The shifted buckets allow to evenly grab and spread the dewatered material.
Deflectors inside the wheel, constructed as elongated suction chambers, dewater effectively the carried out solid material.
In the upper part of the tube the separately controlled discharge channels are installed. Special form and their large quantiy provide steady water drain, and as a result, the less sand loss.
