Spiral Classifiers. The shape of the spiral classifier tanks is usually rectangular (Figure 13.1). The feed is introduced at a position about halfway along the length of the settling tank. The tank slopes range from 14° to 18°. The slope is adjusted such that the top end is higher than the height of the overflow weir. The spirals impede the ...

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.

CLASSIFIERS
CLASSIFIERS. Classification is a process of dividing a particle-laden gas stream into two, ideally at a particular particle size, known as the cut size. An important industrial application of classifiers is to reduce overgrinding in a mill by separating the grinding zone output into fine and coarse fractions.
