Common spiral classifiers include high type and submerged type. The high type is usually used for coarse-grain classification, and the diameter of the overflow particle size of the classification is generally greater than 0.15mm. The submerged type is suitable for fine particle classification, and the overflow particl…

In general, the motion of particles depends on the particle properties (size, density and shape), the operating conditions as well as the slurry density and flow rate (Atasoy & Spottiswood, 1995). Spiral design (trough shape, inclination, number of turns) also plays a significant role in particle separation (Holland-Batt, et al., 1984).
