<p>IMPROVEMENTS IN OR RELATING TO MAGNETIC SEPARATORS The magnetic separator comprises a magnet for establishing a magnetic field in a first zone and a separating chamber. The separating chamber is elongate and is provided with an inlet and an outlet for fluid. Within the separating chamber is a fluid-permeable packing of magnetisable material. At least parts of the separating chamber in the vicinity of ends of the separating chamber are constituted by ferromagnetic material. These parts would otherwise occupy a region of relatively low magnetic field intensity when a magnetic field was established in the separating chamber by means of the magnet. The magnetic separator also comprises means for moving the separating chamber and the packing into and out of the first zone.</p> |
