General
The Magnetic Drum
Separator is often necessary insurance in any
ferrous foundry operation against the potential
damage to “downstream” equipment caused by tramp
metal or other ferrous metallic objects that might
bypass any faulty or inadequate screening in the
shakeout area.
The unit is normally
(in a chemically bonded system) located at the
discharge end of a lumpbreaker where the sand lumps
have been reduced to grain-size. As the sand spills
over the edge of the discharge chute of the
lumpbreaker, it is fed into the inlet hopper of the
magnetic drum separator from where it is gravity fed
to the drum which is revolving around a sectional,
stationary, permanent magnet.
The magnetic field
attracts and holds ferrous particles to the outer
surface of the drum while the non-magnetic material
falls freely from the drum surface down a discharge
chute for sand only. The ferrous particles are
carried beyond the magnets’ influence where they
fall off and down a separate chute dedicated to trap
ferrotic material. The unit provides not only
excellent separation, but controlled feed.
The section of the
hopper that surrounds the drum is manufactured from
non-magnetic stainless steel to prevent induced
magnetism. The inlet chute of the unit is designed
to direct the flow of incoming material across the
face of the drum, providing increased efficiency of
separation. The design also prevents heavier pieces
of metal from hitting and damaging the drum surface.
NOTE: To avoid
problems both in the Cooler/Classifier and the
molding area from undesirable contaminants that
might be found in either the new or reclaimed sand,
we strongly recommend the inclusion of a screen in
the intake of the Cooler/Classifier. Over the years
we have found that these screens are invaluable in
saving on maintenance in the form of “clean-out”
time.
