A Sand Classifier used for separating crushed sand from natural mud or slit,is based on the principle that the former is heavier than water but the latter is not.
Slit 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.
The sand classifier machine consist of an inclined screw conveyor with a water jacket. Water is retained till a particular level.
The mixture of slit and sand is fed at the feed 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 bottom part of the trough of screw conveyor and is conveyed at the discharge end for collection/stacking.
Available in more than one pattern with gear box.
