Abstract:
A method for comminuting, dehydrating, and enhancing paramagnetic susceptibility of material and comprising the steps of:(a) providing an apparatus having: (1) a first cyclone structure having a first material outlet; (2) a second cyclone structure: (3) a blower unit; (4) a conduit assembly forming an air flow path from said blower unit past said first material outlet to said second cyclone structure and to said first cyclone structure; and (5) a material entry port communicating with said conduit assembly between said second cyclone structure and said first cyclone structure; (b) causing airflow from said blower unit to flow through the apparatus; (c) introducing material through said material entry port for entrainment in air flow through said conduit assembly to said first cyclone structure for a first stage of comminution, dehydration, and paramagnetic susceptibility enhancement therein, entrainment in air flow in said conduit assembly to said second cyclone structure for a second stage of comminution, dehydration, and paramagnetic susceptibility enhancement therein; and (d) adjusting said airflow through said apparatus to produce a particle size of said material which is passable through a mesh screen having a size within a range of 50 to 600.
