IMPROVED COLLECTION SYSTEM FOR A WET DRUM MAGNETIC SEPARATOR

摘要

An improved collection system for a wet drum magnetic separator including a tank for receiving a flow of a mixture of magnetic and non-magnetic parti cles in a feed port. A collection system includes a rotating drum having a r oughened collection surface disposed in the tank, an array of permanent magn etic elements disposed inside the drum arranged in a fixed position relative to an azimuthal section of the drum for establishing an azimuthal magnetic interaction region defined by a level of the mixture in the tank for attract ing the magnetic particles to the roughened collection surface, a non- magne tic particle discharge port located on an opposite side of the tank that rec eives the flow for removing the non-magnetic particles, a magnetic particle discharge port located outside the tank for receiving the magnetic particles , and a magnetic particle removal subsystem for removing the magnetic partic les trapped in the roughed collection surface and dispensing the magnetic pa rticles to the magnetic particle discharge port.
