Magnetic separators with flow velocity decreasing while flowing through medium

Abstract From the Canadian patent

A magnetic field is established in a first zone by a magnet. Fluid containing magnetisable particles is passed through a separating chamber disposed in the first zone. The separating chamber comprises a rigid elongate canister having an inlet and an outlet for fluid, at least two fluid-permeable partitions dividing the space within the canister into several compartments, each of which extends substantially the full length of the canister, and a packing of magnetisable material disposed between the partitions. The form and disposition of the canister, the partitions and the packing material is such that the fluid flows from the inlet, through the packing material in a direction transverse to …
