Title:
MAGNETIC SEPARATOR
Document Type and Number:
WIPO Patent Application WO/2013/145872
Kind Code:
A1
Abstract:
[Problem] To provide a weak magnetic force magnetic separator that recovers ferromagnetic bodies by magnetization recovery and also does not magnetize and recover weakly magnetic bodies.
[Solution] This weak magnetic force magnetic separator has a conveyor belt that conveys particles to be separated and a suspended magnet unit provided with intervening space above the conveyor belt, and the magnet unit magnetizes the particles to be separated, which are conveyed on the belt, with a low magnetic force without variations. The magnetic separator is characterized by the variations in the magnetic flux density on the surface of the belt facing the magnet unit being 10% or less in the direction of belt width in a weak magnetic force range of over 0 to 700 gauss by the length of the magnet unit in the longitudinal direction being greater than the width of the belt, the longitudinal direction of the magnet unit being aligned across the width of the belt, the two ends of the magnet unit being made to protrude more than the width of the belt, and the distance of the intervening space from the surface of the belt being made a fixed distance across the longitudinal direction.
