Sand Classifier

Listing ID #373936

We offer Sand Classifiers which are used for the separation of crushed sand (stone particles below 3 mm.) from natural mud or silt, is based on the principle that the former is heavier than water but the latter is not.
Silt mixed crushed sand if used for making concrete yields low strength and hence this machine is particularly useful for obtaining crushed sand for use in high strength concrete.
Our Sand Classifier consists of an inclined screw conveyor with a water jacket. Water is retained till a particular level.
The mixture of silt and sand is fed at the feed (lower) end of the inclined screw conveyor. The silt particles being lighter than water do not settle down and are drained away with water. The crushed sand being heavier than water settles on the bottom part of the trough of the screw conveyor and is conveyed at the discharge end.
