modelling and simulation of spiral classifiers

May 26, 2016 Spiral Classifier. In mineral processing, the Akins AKA spiral or screw Classifier has been successfully used for so many years that most mill operators are familiar with its principle and operation. This classifier embodies the simplest design, smallest number of wearing parts, and an absence of surge in the overflow.

    2. Numerical Methods. The mill geometry used for the simulations is based on the Hosokawa AS50 spiral jet mill. However, the geometry is based on an in-house drawing made at the University of Leeds and shown in Figure 1 [28,29].The milling chamber is 50 mm in diameter and has four jets angled at 50 ∘ from the radius. A special feature of the AS50 is its classifier design.

    A preliminary mathematical model for the spiral was developed [7] [10] and programmed into a simulator for a gravity circuit in order to assess the previous options before moving to full scale evaluation. The spiral model accepts changes to the wash water additions and to the opening of the discharge splitter (Figure 1(f)). The input variables for the simulator are:
