spiral classifiers. A spiral classifier is a mineral processing equipment which receives an ore slurry input and performs a gravity separation process between the solids particles of ore and the water. The classifier has two outputs: the "underflow", formed by sedimented coarse solids; and the "overflow", in the
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.
