The design of these classifiers (rake, spiral, screw) have inherent problems, First, they are very susceptible to wear, caused by the scrubbing action of the ore, that plus all of the mechanical moving parts create many worn areas to contend with. The other problem that these classifiers have is that they are easily overloaded.
Screw Classifier. Screw classifier are an effective way to wash, dewater, deslime and control the bottom end of the gradation. A large pool area provides maximum retention of desirable product sizes, while a rising current system floats off the excess "fines".

The grit classifier is effective over a wide range of grit particle sizes, including sugar sand. When the grit slurry is transferred to the grit classifier, the inlet flow is directed diagonally downward. As grit settles, a shaftless screw carries the grit from the bottom of the hopper to the discharge, further washing and dewatering it.
