PRODUCTION OF MAGNETIC DISC FOR ACTIVATED SLUDGE MAGNETIC SEPARATOR

摘要

PROBLEM TO BE SOLVED: To provide a method of producing a magnetic disc for an activated sludge magnetic separator by which the magnetic disc of high magnetic separation capacity can be produced. SOLUTION: Magnets 2 are arranged on an iron plate 1 as arranged on a magnetic disc, also these magnets 2 are surrounded by an outer frame mold 3 having the size corresponding to the outer peripheral surface of the magnetic disc and resin is made to flow into the outer frame mold 3 to solidify it. Since on the obtained magnetic disc, magnetic pole surfaces 2a, 2a of the magnets 2 are projected out of the surface, magnetic separation capacity is high. At the time of the production, since the magnets 2 are attracted on the iron plate 1, the arranging is easy.
