The spiral chute is mainly composed of six parts: a feeding homogenizer, a feeding groove, a spiral groove, a product intercepting groove, a receiving hopper, and a groove support. When a certain concentration of slurry is fed into the upper part of the spiral ore separator, the slurry rotates downward along the spiral groove.

Only enough water is necessary to keep the solids in full teeter. As the sands accumulate in the classifier pockets the effective density of sand-water mixture increases and thumbscrews on the valve rod assemblies may be adjusted to discharge sand from each compartment as required. The finer the sand the less water is required.
