PERMA DRUM
INSTRUCTIONS
DESCRIPTION
The Perma Drum is a self-cleaning permanent magnet type
magnetic separator. It’s designed to protect processing machinery
against damage from tramp iron, and to protect processed materials
against ferrous metal impurities.
The Perma Drum operates with a motor driven stainless steel shell
that revolves around a stationary internal magnet assembly. Material
to be separated is fed against the shell. Magnetics in the feed are
attracted to the shell, and held against it until reaching a discharge
location. Here the separated magnetics are automatically released.
This type separator is manufactured in 2 models. One, the Type PC,
includes the magnetic drum, but not a housing or drive motor. The
other model is the Type FC. It does include a housing and a drive
motor with the magnetic drum.
IMPORTANT
This installation bulletin has 2 sections. Section 1 covers the Type
PC only. Section 2 covers the Type FC only. Read Section 1 before
installing a Type PC. Read Sections 1 and 2 before installing a
Type FC.
OPERATING TEMPERATURE
• Operating temperature for ceramic magnets is -40°F through 250°F
(-40°C through 120°C).
• Operating temperature for rare earth magnets is 176°F (80°C) or less.
NOTE: Extreme temperatures may affect the performance of the
magnet. Refer to Bulletin 1214T.
SECTION 1
MOUNTING - TYPE PC
Check all packaged material for shortage of parts and possible
damage. Report shortages or damage to the delivering carrier.
Use care in uncrating to avoid damage.
The Type PC is shipped fully assembled and ready for mounting.
Mount it by supporting it on the drive side (the keyway in shaft side)
with a pillow block bearing, and on the opposite side with a shaft
clamp.
The pillow block bearing allows the drive side shaft to turn, and
the drum shell to revolve around the stationary internal magnet
assembly. The shaft clamp holds the internal magnet assembly in
place. A pillow block bearing and a shaft clamp are optional items
available from Dings.
ADJUSTMENT OF MAGNETIC ARC - TYPE PC
After the drum is mounted, adjust the position of the magnetic arc,
as shown in Figure 2. This is done by adjusting the location of the
internal magnet assembly, using a steel rod to turn the shaft. Insert
the rod into the hole that’s in the shaft extension on the non-drive
side. Move the rod to rotate the magnet assembly upward until you
can feel the magnetism in the strongest part of the magnetic arc at
the 3 o’clock position. Then, hold the rod in place and tighten the
shaft clamp.
