Graymills Bed Filter Magnetic Seperator OMI - Manual (Page 2)

SYSTEM FEATURES
The Graymills combined Coolant Tank, Bed Filter and
(optional) Magnetic Separator are designed to keep your
cutting, grinding, drilling and milling machinery operat-
ing at peak performance. By filtering out harmful conta-
minants, coolant life is greatly extended, saving both
replacement and labor costs.
Coolant flows into the diffuser tray, which separates larg-
er chips and milling by-products. The liquid then pours
onto the filter bed where it is sieved by the filter media.
As the contaminants accumulate and clog the filter
media, the solution rises in the filter bed until the float
switch is triggered. This starts the motor that moves the
chain conveyor/filter media along, until it is replaced with
clean material. The soiled filter media is moved to a
sludge box.
The benefits are:
• Keeps the coolant clean. Reduces frequency of coolant
replacement. Reduces operating costs.
• Keeps the workpiece surface cleaner.
• Grinding wheel does not need to be dressed as often.
Increases productivity and grinding wheel life.
SYSTEM COMPONENTS
A Pump
Used to deliver the coolant in the tank to the machine.
B Gear reducing motor
Moves the filter media along as necessary.
C Liquid Level Control
Float switch mechanism controls the level of coolant
collected in the filter valley. Switch operates the motor
that moves the filter media along.
D Diffuser Tray
Collects larger particles before the coolant is deposited
on the filter media. Also helps spread deposits evenly,
increasing media life.
E Filter Media
Collects the particles to filter the coolant. Standard roll is
rated at 20 micron. Other micron ratings available; con-
tact Graymills for details. 150 yard rolls.
F Sludge Box
Used to accumulate spent filter media and prevent run off
to floor.
G (Optional) Magnetic Separator
Removes ferrous material from coolant before straining
for other debris. Can be installed directly on bed filter for
dual stage separation, or run independently with pumping
system.
SET UP AND INSTALLATION
Coolant Tank and Bed Filter
1.Unpack and inspect unit carefully to verify that every-
thing is intact and there are no obstructions in the chain
mechanism or any other electrical or mechanical com-
ponents. Do not run power to system at this time.
2.Position the unit in the area in which it will be operating.
3.Remove diffuser tray and lids from paper compartment
and chain area.
4.Fill the tank cavity with coolant until level is approxi-
mately 1 to 2 inches below side wall of tank, being
careful not to overfill.
5. Proceed to feed paper through the opening at the bot-
tom of the paper compartment and onto the chain until
the chain is completely covered. Extend filter media a
few inches past the chain. Position the sludge collection
box at the end of the tank and place end of filter paper
over box so soiled media drops into box.
6. Replace lids and reinstall diffuser tray.
7. Pump and bed filter may be wired sepa-
rately in the event there is a power feed
from your machine tool to incorporate
the pump operation into the main
control. If not, you may run a
water-tight conduit (customer sup-
plied) from the pump to the main
control box and bring your main
power feed into it for a central con-
nection. All electrical work must be
according to applicable codes.
8. Make the necessary connections
