A semi-empirical mathematical model for a spiral classifier is proposed in this paper. The model is based on the observations of the movement of particles within the trough of a spiral and makes use of several hypotheses that still need to be validated with dedicated experiments. The objective of the model development was to allow the ...

Spiral classifiers. A typical spiral classifier is shown in Fig. 1. The geometry of a spiral is characterized by the length or number of turns, the diameter, the pitch and the shape of the trough (Burt, 1984). The spiral feed is a mixture of water and ground particles that is gravity fed at the top of the spiral.

Spiral classifier uses the principle of the proportion different of solid particles, so the precipitation speeds is also different in the liquid. Fine mineral particles float in the water and overflow; the coarse ore particles settle on the bottom of the channel. Material is discharged from the upper by spiral, so as to finish the grading work.

When and Where to use a Screw-Spiral Classifier Closed Circuit Ball Mill or Rod Mill Grinding. Most efficient grinding is effected by removal of material from the ball mill as soon as it has been reduced to the required size. This eliminates over-grinding and permits utilizing all of the power applied to the ball mill in actually grinding the ...
