Dings Magnetic Group 2 PULLEY EDDY CURRENT SEPARATOR - Manual (Page 6)

MAINTENANCE
CAUTION: Rare earth magnets in the magnetic
rotor assembly are extremely powerful. They can
project magnetism through a considerable dis-
tance and exert strong pulling force on magnetic
metals. Use of iron or steel tools near the magnet
could cause injury to personnel or damage to the
separator.
I MPORTANT D AILY M AINTENANCE
The magnetic rotor should be inspected routinely to ensure
that no iron or ferrous metal is attached to the shell of the
rotor beneath the conveyor belt. This metal may wear a
groove in the surface of the outer shell and cause it to fail
prematurely. Daily inspection is recommended, although it
depends on your application and conditions.
The ceramic tile used by Dings on the outside of the
fiberglass shell is the most wear-resistant surface available,
but you will still need to inspect the shell daily and remove
any iron particles in order to ensure a long life for the sepa-
rator.
To inspect the wear shell:
1) Turn off the magnetic rotor and the conveyor belt
and lock out power. Allow them both to come to a
complete stop. The conveyor belt will continue to
run for several minutes after the switch has been
turned off. Lock out power.
CAUTION: You should wear safety glasses,
a face shield, or some other type of eye
protection before proceeding with the
inspection.
2) Open the access doors (Fig. 10) and inspect the belt
and the wear shell. There should not be any holes in
the belt, nor any grooves in the wear shell of the
rotor.
3) Rotate the shell slowly by hand and remove any
iron particles which may be attached to it.
4) Continue to rotate the pulley slowly and remove
any pieces of steel or iron sticking in the belt.
Inspect the belt for any signs of holes or wear
which may allow particles or iron to go through
the belt and onto the surface of the wear shell.
If the belt shows much wear or any holes,
it should be replaced with a new belt.
5) Inspect the belt position on the pulley to see if it
is tracking properly or if it needs to be adjusted.
Do not over-tighten when adjusting or damage
will occur to the wear shell.
6) Inspect the belt slider bed through the access
doors. If the slider bed shows signs of excessive
wear, it should be replaced.
Cleaning the Splitter
CAUTION: Stop the separator before cleaning
the splitter. It is dangerous to clean it when the
unit is running as the cleats on the belt may
cause injury. Lock out power.
It is very important to keep paper, rags, wire, plastic
bags, etc. from collecting on the splitter. This build-up
of debris can block the nonferrous metal, causing it to
fall into the nonmetallic discharge chute. To clean the
splitter:
1) Turn off the magnetic rotor and the conveyor
belt. Allow them both to come to a complete
stop. The belt of the conveyor will continue to
run for several minutes after the switch has
been turned off. Lock out power.
2) Open the two Lexan access doors on the side
of the discharge housing.
3) Use a wooden stick or dowel to clean off
the splitter.
CAUTION: Do not use a metal rod or any piece of
steel or iron as it will be attracted to the magnetic
rotor.
