FLUIDIC SEALING SYSTEM FOR A WET DRUM MAGNETIC SEPARATOR

摘要

A magnetic fluidic and a mechanical fluidic sealing system for a wet drum magnetic separator including a tank for receiving a flow of a mixture of magnetic and non magnetic particles, a rotating drum disposed in the tank, an array of permanent magnetic elements disposed inside the drum arranged in a fixed position relative to a azimuthal section of the drum for attracting the magnetic particles to the surface of the drum, and at least one seal disposed proximate each axial end of the array concentrically shaped and spaced from the surface of the drum and extending to a bottom wall of the tank for establishing a magnetic fluidic seal and/or a mechanical fluidic seal between the surface of the drum and an inner concentric surface of the seal that maintains the magnetic particles inside the magnetic field of the array and reduces end losses of the magnetic particles.
