The basic principle of a Knelson Concentrator (KC) is the differential settling velocities of particles in a medium under a centrifugal field. Whether the ore particles remain in the KC bowl depends on the terminal settling velocity (v) of the particles and the fluidization water flow velocity (V). Both variables are functions of the material ...
