Air classifiers use the spiral air flow action or acceleration within a chamber to separate or classify solid particles. Powders suspended in air or gas enter the cyclone and the heavier particles spiral out and down where they are collected. The air and finer particles flow up to the top where they may be passed to another cyclone with finer ...

This classifiers are of the spiral and screw family. It is of interest that the Homestake, long a user of cones for dewatering and classifying, selected mechanical bowl classifiers for their new mill addition. In the Homestake's enlarged and rearranged plant are 10 cones of local make, 7 ft. in diameter and with 65-deg. sides.

The Spiral Classifier is available with spiral diameters up to 120″. These classifiers are built in three models with , 125%, and 150% spiral submergence with straight side tanks or modified flared or full flared tanks. The spiral classifier is one of the size-classifying equipment for the mining industry.

Spiral Classifier. Spiral classifier is used for material classification with spirals used to stir and convey materials according to the difference in material settling velocities. It is a kind of gravitational and hydraulic classifiers. The specification of spiral classifiers is represented by the number and diameter of spirals.

The data set is well balanced by design, it has 1 200 data points and 3 classes (400 per class). A linear classifier would be very bad in classifying this data set as it is impossible to divide data points by lines as you can see in the image below. It is a 33.33 % probabilty (400/1200) to classify a data point correctly and this is our ...
