DRY SEPARATORS
For information on purchasing or licensing opportunities, contact Dr. Robin R. Oder at roder@magneticseparation.com.
Magnetic separator chain used in the MagMill configuration. It consists of a belt separator to remove strongly magnetic contaminants. The product of the belt separator is fed to the second stage electromagnet for removal of feebly magnetic contaminants.
Stand-alone belt separator. One version was tested in processing coal, fly ash, and nickeliferous-pyrrhotite. The ElectriMag version combines the belt magnetic separator with dry triboelectric separation.
3,000 lb/hr MagMill prototype. A pilot unit was operated at the DTE Energy Services Petcoke Grinding Facility in Vicksburg, MS from 2007 - 2011 where coals from throughout North America were tested.
VacuMag Separator for recovery of magnetic components from fly ash.
HYDROCARBON LIQUIDS
Apparatus for removing strongly magnetic particles from viscous flows. A 50 barrel per day prototype was tested in separation of sub-micron sized iron catalysts from 500oF Fischer-Tropsch wax. The patents pertaining to this process have been sold to a major developer of coal-to-liquids technology.
Photo of effect of magnetic field on particle shape using Magnetostatic Coalescence to break emulsions. Tested in recovery of naphthenic and cresylic acid from emulsions made in caustic dewatering of crude oil.
