Sandtec – Sand Recovery Group With Hydrocyclone

Hydroplane based washing unit

HOW IT WORKS: The slurry composed of a mixture of water, sand, silt, clay, etc. is conveyed to the storage tank through the feeding chute (A).

The pumping unit (B) positioned in the lower part of the tank sucks up the slurry and sends it to the hydrocyclone through a pipe in antiwear rubber with metal inserts (C).

The hydrocyclone (D), thanks to a centrifugal movement, causes the liquid-solid separation.

The underflow, composed off a mixture of sand over 75 microns, about 30% of the treated water is sent to the Dewatering Screen (E).

The overflow, containing particles under 0,1 mm only, is sent to the Water Discharge Chute (F), where the water discharge pipe will be fitted, but which also acts as compensator in case the level of the input water is below that of the treated water.

The Dewatering Screen fitted with a polyurethane Draining Deck drains the sand and sends it to the Sand Discharge Chute (G).
