Abstract
A magnetic separator, for separating magnetizable particles from a fluid, consists of a separating chamber filled with a paramagnetic packing material, and a magnet for establishing a magnetic field within the packing material. The packing material is pervious to the fluid. A process for separating magnetizable particles from a fluid consists in applying a magnetic field to the packing material while passing the fluid therethrough, so as to attract the magnetizable particles in the fluid to collecting sites within the packing material.
Claims2
In a magnetic separator for separating magnetizable particles from a fluid having such particles in suspension therein, the separator comprising a separating chamber having an inlet and an outlet for a fluid, a packing material which is pervious to the fluid disposed within the separating chamber between the inlet and the outlet, and electromagnetic means for establishing a magnetic field in the region of the packing material within the separating chamber, the improvement which comprises the packing material being paramagnetic at normal operating temperatures and normal operating magnetic field intensities, said chamber additionally being provided with a packing material, which is pervious to the fluid and which is ferromagnetic at normal operating temperatures and normal operating magnetic field intensities, disposed between the paramagnetic packing material and the outlet.
