An operational model for a spiral classifier

Most of the models for spirals are fundamental and use a balance of forces to calculate the equilibrium position of a particle as it flows down the trough of a spiral (Das et al., 2007, Holland Batt, 1989, Holtham, 1992a, Holtham, 1992b, Kapur and Meloy, 1999, Sivamohan and Forssberg, 1985).
