The grit classifier consists of a sloping bottom tank and a screw conveyor. The grit settled at the bottom of the tank is collected, lifted by the screw conveyor and then drained and discharged. The screw diameter and consequently the grit classifier model varies according to the volume of grit to be dewatered.

Spiral classifier is widely used in beneficiation plant to match with ball mill to form a closed circuit circulation path to distribute ore sand. Filter the material powder milled in the mill, and then use the spiral piece to screw the coarse material into the ball mill inlet, and the filtered fine material is discharged from the overflow pipe.

Screw classifier. Screw classifiers have been used for quite some time in the mining industry, they are generally installed on an incline so for example the sand being processed is corkscrewed up to a discharge while in the lower reaches there is a bath of water that washes the sand of silts and clays and discharges down the lower reaches.
