<p>The metal separator has a metal detector (2), in front of a suction jet (5), for removal of detected metal elements, controlled by an evaluation stage (9), receiving the metal detector signal.Pref. the suction jet is coupled to a suction line (6) of a suction conveyor (11), containing a magnetically-operated valve (10), controlled by the evaluation stage, together with a second magnetic valve (16) in a connection line (17) between the suction conveyor and an air line (7) extending parallel to the material feed direction.</p> |
