An operational model for a spiral classifier
2. 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.

to settle. The settled grit travels up the spiral conveyor where it is de-watered and then discharged as a low moisture product ready for final disposal. The balance, containing light organics and grit finer than 150 mesh, flows over the classifier overflow at the end of the classifier where it can be piped for further treatment. 1. Cyclone ...

Features of Hand-Drawn Spirals for Recognition of Parkinson …
Abstract. In this paper, a method for diagnosing Parkinson's disease based on features derived from hand-drawn spirals is presented. During drawing of these spirals on a tablet, coordinates of points of the spiral, pressure and angle of the pen at that point, and timestamp were registered. A set of features derived from the registered data ...
Rake Classifier
rake classifier mechanism. The rake classifier (Figure 9.18(a)) uses rakes actuated by an eccentric motion, which causes them to dip into the settled material and to move it up the incline for a short distance.The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated. The settled material is thus slowly moved up …
