Spiral operation and partition curves of the particles. A spiral classifier is shown in Fig. 1. The spiral feed that consists of a water-slurry of ground ore enters the top of the spiral. As the slurry enters the spiral various forces (Burt, 1984) act on the particles to operate the separation between light, heavy, coarse and fine particles.

Nesans Spiral Classifier consists of an open trough with a chute provided for the input feed material. Before being fed into the spiral classifier, the dust from the screen is mixed with water and it is carried to the input chute through a slurry pump. The inlet flow is evenly distributed across the surface area of the spirals.
