Abstract
In apparatus for removing water and impurity components from sand, there are provided a rotary member having an opening at one end for charging and discharging sand and a filter for passing water. The rotary member is supported by a support and driven by a variable speed motor. Piston-cylinders or the like are provided for tilting the support. In a modified embodiment, two of the rotary bodies are juxtaposed with their openings faced each other. A peripheral wall of the rotary member is provided with a member of perforations for discharging water separated from sand.
