Abstract
Apparatus for treating the magnetic properties of particles while the particles are suspended in a circulating stream of air or other fluid. The apparatus causes particles to rotate around a vertical axis in confined circular paths of travel generally lying in a horizontal plane.
Claims2
Particle treatment apparatus including
- (a) means for forming in a volume of fluid a funnel having an upper portion, a lower portion, a core region, and a vortex region of fluid circulating around said core region, said means including
- (i) a hollow cylindrical member having first and second inlet and outlet ends and a vertical axis,
- (ii) means for rotating said cylindrical member about said vertical axis to cause fluid to circulate around said axis, and
- (iii) means for drawing fluid through said rotating cylindrical member in a direction of travel from said second end to said first end;
- (b) means for introducing particles into said vortex region, said vortex region causing said particles to rotate around said vertical axis in confined circular paths of travel lying in said vortex region and in a horizontal plane;
- (c) particle treatment means for altering the magnetic properties of particles carried in said vortex region.
