NONFERROUS METAL SCREENING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a nonferrous metal screening machine having a drum reduced in abrasion and having long life and a raw material charging feeder of which the leading end portion is not overheated. SOLUTION: In a nonferrous metal screening machine 10 having a rotary drum comprising an insulating material and rotationally driven at a low speed, a feeder 16 supplying a raw material to the upper part of the rotary drum 14 and the high speed rotary magnetic pole body provided in the rotary drum and attached so as to be eccentric upwardly, a large number of abrasion- resistant ceramic plates or rubber plates are bonded to the periphery of the rotary drum 14.
