The Effect of Particle Size Distribution and Liberation ...

2020-10-27  Spiral concentrator is a gravity separation equipment, consisting of a spiral channel connected to a vertical support. Separation of particles in spirals is based on particle size and density and the combined effect of gravitational forces, centrifugal forces, drag, and Bagnold forces (forces related to Newtonian fluid) on the particles [1,2,3].As the pulp enters the spiral channel, smaller ...
