Abstract
A magnetic separator comprising a vibratory conveyor for vibratorily flowing non-ferrous articles and articles containing ferrous material within the magnetic field of a transverse extending magnet to magnetically capture the articles containing the ferrous material while allowing the non-ferrous articles to flow therepast. The magnet is periodically retractable to remove ferrous articles magnetically adhered thereto. The use of a set of transverse extending magnets enables a continuous on-the-go separation of articles containing ferrous material from non-ferrous articles without having to shut down the vibratory conveyor.
Claims5
A method of separating articles containing ferrous materials from articles containing non-ferrous materials comprising the steps of:
- placing a batch of articles containing ferrous materials and non-ferrous materials on a vibratory support;
- placing a set of vibratory trays in series and placing a set of magnetic members transverse to the vibratory flow of the batch of articles from tray to tray;
- vibrating the vibratory support to bring the batch of articles deeper into a magnetic field of a magnetic member of the set of magnetic members;
- magnetically capturing the articles containing ferrous materials on the magnetic member as the ferrous articles vibratory flow past the set of magnetic members while the articles containing non-ferrous materials bypass the set of magnetic members;
- and
- removing the articles containing a ferrous material from one of the set of magnetic members while maintaining the remaining magnetic members of the set of magnetic members in a magnetic grasping position to thereby allow the articles containing ferrous materials to be removed from the vibratory flow without interrupting the vibratory flow of the batch of articles.
