Abstract
Official abstract text for this publication.
A magnetic drum separator ( 2 ), with a drum ( 6 ) rotatable about a rotational axis ( 4 ), a magnet arrangement ( 10 ) of a plurality of magnets ( 12 ) arranged in the interior ( 8 ) of the drum ( 6 ), a separation zone ( 18 ) in the exterior space ( 14 ) of the drum ( 6 ); a feed material ( 22 ) flows through the separation zone ( 18 ) and is there separable with the aid of a magnetic field ( 26 ) generated by the magnet arrangement ( 10 ), into a waste stream ( 30 ) and a recyclable material stream ( 28 ). A relative position (R) of at least one of the magnets ( 12 ) relative to the rotational axis ( 4 ) can be varied. A nominal magnitude (S) for a process value ( 78 ) on the drum separator ( 2 ) that is influenced by the separation behavior ( 32 ) is specified. At least one measurement device ( 74 ) detects an actual magnitude (I) of the process value ( 78 ), and a controller ( 82 ), which changes the relative position (R) of the at least one of the magnets ( 12 ), whereby the actual magnitude (I) is controlled to approach the nominal magnitude (S).
First claim
Opening claim text (preview).
The invention claimed is: 1. A magnetic drum separator comprising: a drum which is rotatable about an axis of rotation; an interior space in the drum; an arrangement of magnets having a plurality of the magnets arranged within the interior space in the drum; a separation zone located in an exterior space outside the drum, and configured for material to be processed to flow through the separation zone; the arrangement of magnets producing a magnetic field operable for separ…
