CLASSIFIERS
The feed is given a high tangential velocity and is introduced near to the top of the unit. The gas flows in a spiralling fashion towards the bottom end where it experiences a flow reversal and passes up as a central core. In the cone classifier, the central core of gas actually flows in a reverse spiral up the wall of a central feed.

2. Floor area. Obviously, the footprint of the hydrocyclone is significantly smaller than that of the spiral classifier. Usually, the area of the hydrocyclone is only 1/30～1/50 of the spiral classifier. The equipment footprint requirements also limit the application of spiral classifiers to a certain extent. 3.

Principles of Spiral Gravity Classification
if the cylinder diameter is 100mm, the formed spiral diameter is 500mm and a 45˚ inner slope is involved then the downward slope of the outer edge would be 11.3˚ (see fig.4, yellow angle). The formed spiral would also slope inwards towards the supporting cylinder. This is the important angle β of fig.1 and is given by: tanβ = 2(D2-D1) (5 ...
