Cleaning if rotor is mounted to housing
1.
Stop the production process before turning off the device.
Wait till the last amount of raw product has left the outlet canal.
2.
Stop the motor/rotor.
3.
Wait till the rotor has completely stopped and then open the housing door by first loosening the
fastener clamps.
4.
Remove all rotor parts, including the extractor and magnet bars. DO NOT pull the magnets out while
still in the product chute; this will cause Fe particles to fall into the outlet canal.
5.
Place the rotor on a non-magnetic underground.
Pull the magnets out by placing your thumbs into
the holes and pulling the magnet flange with your
fingers.
6.
Pull the magnet bars out of the extractor and place
them - not in the neighbourhood of ferromagnetic
materials – far enough away from the extractor. The
iron particles will fall of from the extractor and can
be caught and removed.
7.
Clean the magnet bars and the inside of the extractor tubes thoroughly to avoid the magnet bars to get
‘stuck’ in the extractor tubes after mounting. Cleaning is best done with pressed air and/or soft clothes.
If you choose to clean with a solvent, then be sure to replace the parts fully dry.
8.
Replace the magnets into the rotor. Possibly the magnet bars have to be slightly “guided” into the
extractor holes.
9.
Shove the entire rotor over the axle in the housing, until the rotor is fully inside the housing. You will
feel the rotor to clamp over the axle.
10.
Close the door, tighten the fasteners,
11.
Re-start the motor and then Re-start the product flow.
Take care that the Fe parts on the extractor tubes do not ‘shoot’ to the magnet bars, while it will be very
difficult to remove them from the magnets afterwards!
