Abstract
This report describes the application of pulsed magnetic fields derived from alternating and intermittent magnetizing currents. Application of such pulsed magnetic fields to the matrix-type separator permits (1) the complete discharge of the magnetic fraction with wet feeds and (2) the dry separation at particle sizes down to 325 mesh. At smaller particle sizes, indications are that frequencies above 60 hertz will be required. Applications of intermittent magnetizing current to the crossbelt separator give the crossbelt separator an advantage over the conventional constant- field crossbelt and induced roll separators; the intermittent current enables the crossbelt separator to separate matted fibrous and magnetically coagulating feeds, a type of feed that occasionally occurs with mineral, industrial, and secondary materials.
