Over Band magnetic Separator is more maintenance oriented compared to Suspended magnets.

Imagine the suspended magnet is fixed on a motorized trolley.

Then we need a program like this :

1. This motorized trolley moves away from the conveyor as per preset time

2. Demagnetize to unload the picked up material in a collection bin

3. Comes back in position

4. Again getting on

This timing may be variable, as per the foreign ferrous materials present and the conveyor may be stopped when the suspension magnet moves away from the conveyor.

Is there any manufacturers who have such products ?

I used heavy Eriez magnets on a trolley over a conveyor. When the conveyor shut down it would move the magnet out along the trolley with a motorized chain fall drive and hit a limit switch at the end of travel de-energise the magnet to dump any metal into a container and stop the trolley motor. When the conveyor started up the magnet would re-energise and move back into position over the conveyor and stop at the end of travel switch.

There was also a manual override that would allow anyone to dump it. When the container was full mine services would replace it with an empty one. This worked out very well for us.

It would cost an arm and a leg to have the magnet companies design one for you when they are so simple to design. Very simple to set up and tie the logic to the conveyor IO rack. ■
