ABSTRACT
To manipulate the separation density of a dense medium cyclone (DMC), different arrangements of permanent magnets were attached on the outside of the cyclone. Separation tests were performed and the results showed that, with the increasing magnetic field intensity, the products densities decreased with magnetite only, and the separation density first increased and later decreased. The simulation analysis indicated that the presence of a magnetic field in the lower conical section of the cyclone can decrease the separation density, because of the downwards movement of the magnetic medium. This paper proposed a new magnetic manipulation method for separation density and also will be an innovative way to increase the capacity of the equipment.
