GENERAL

Uk1-allg_030107–Pre

Flottweg

Function 1.1/1

The medium to be separated is fed into the decanter through the central feed pipe (1).
The denser solids settle against the bowl wall (2) under the influence of the centrifugal
force.

The two liquid phases (3,4) , which have different densities, form hollow cylinders, the
light phase the inner one, the heavy phase the outer one.

The thickness of the individual liquid rings is determined by the adjustment of the
overflow weir (5) and the variable impeller (6).

The solids deposited on the bowl wall (7) are transported towards the conical end of the
bowl (9) by the conveyor scroll (8) to the discharge ports (10) and discharged into the
solids housing.

Flottweg

Function 1.1/2

The moisture content of the discharged solids and the purity of the liquid can be adapted:

a) by changing the separation line between the two liquids by means of the variable

impeller and a wide selection of phase separation disks:

- lower moisture content of the solids by chosing a larger diameter of the phase
separation disk and thereby increasing the drainage zone

- optimum quality of the heavy phase by maximum difference between the
impeller diameter and the diameter of the phase separation disk

- optimum quality of the light phase by minimum difference between the impeller
diameter and the diameter of the phase separation disk

b) by changing the bowl speed:

- the finer the solids, the higher the bowl speed necessary for satisfactory
separation results.

c) by changing the scroll differential speed:

- the lower the desired moisture content of the discharged solids,
the lower you set the differential speed.

- the higher the solids content in the inlet,
the higher the required differential speed.

Note: The optimum machine setting can only be determined by careful testing.

WARNING

WARNING

Danger at the machine

Rotating parts may bruise or cut off fingers and hands.
Operate centrifuge only with properly mounted safety

The main risk at the machine is the fast rotating rotor and its drive unit.
Rotor, belt drive and motor may bruise or cut off fingers and hands.
Therefore hood and covers must not be removed before the rotor is at standstill.
As a matter of principle, before maintenance and dismounting work, make sure that the
rotor stands still and is secured against restarting.

DANGER

covers!

The solids are centrifuged downwards out of the solids
housing with great power.
Danger of injury to fingers and hands.
Never put your hand into it!
Always take solids samples with suitable tool.

The solids chute has to be lead closed up to the conveyor or collecting tank.
Thereby sound emission is reduced and ejected parts (kernels, stones, etc.) are
prevented from rebounding from the floor and thus causing injuries.

CAUTION

After two hours:

- Either switch the bowl drive off

- or reduce the bowl speed to 30%

- or flush the decanter for cooling

With hydraulic drives oil may squirt out under high pressure
due to damages at individual components.
This may cause injuries especially to the eyes and
poisoning.
In case of contact with skin and eyes take measures as
stated in the provided safety data sheet.

During operation without product the temperature of the
centrifuge can increase inadmissibly high. Therefore the
centrifuge may be operated without product for maximum
two hours.

Flottweg

Safety instructions 1.2/4

Measures in an emergency

In the event of an emergency the machine/facility is to be stopped immediately.
In case of fire, the operating company must provide for the immediate disconnection of
power and other firefighting measures. Fast-running centrifuges can generate large
amounts of heat in cases of extreme damage, igniting flammable substances.
After an emergency shutdown or a power failure, the machine may only be restarted by
hand. An automatic restart is not permitted.

The defects have to be eliminated before starting up again.

Maintenance or dismounting works

Maintenance or dismounting work may only be performed by the operator according to

he instructions and up to the extent stated in the operating instructions. Other

t
maintenance and repair work than described in the operating instructions is only to be
performed by persons which are especially authorised by Flottweg.

No changes, attachments or modifications are allowed to be made to the machine
without the express approval of Flottweg . Original spare parts and accessories
approved by Flottweg will aid safety. The usage of other parts renders void any liability
for the consequences.

Water endangering medium or fuel, if flowing out at maintenance work or through
leakages, must by no means reach the ground or the sewerage system. When
exchanging oil or removing excessive or worn grease, pay special attention to
environmental protection and professional waste disposal.
Substances are to be bound with suitable absorbents immediately.

No objects must be deposited on the machine. They might slip below the protective
covers, be caught by rotating parts and thrown off.

Before maintenance and dismounting work always

- switch off machine

- wait until machine comes to a complete standstill
(depending on the type up to 45 minutes)

- check if rotor stands still (e.g. fan blade at the main motor)

- secure against restarting (e.g. padlocks at the main switch)

Cleaning 2.3

1. Thoroughly clean the decanter immediately after stopping the supply of feed
material and before stopping the motor.

Max. water temperature 80° C.
Water consumption and flushing periods: depending on product
Note: If the decanter is not cleaned as required, restarting will

be complicated, especially after storage periods, due to
product deposits.

2. Cleaning procedures

2.1 Cleaning the bowl interior and the scroll (15 min)

- stop feed / flocculant introduction

- feed water through feed pipe and flush machine

- operate skimmer between min. and max. diameter several times:

at min. diameter liquid will flow through solids discharge openings

after some time and flush the solids housing

- as soon as effluent is clear water:

turn skimmer to max. diameter, stop supply,
turn off decanter and wait until rotor stops,
adjust skimmer to standard diameter

Note: After turning off the decanter, close centrate shut off valve, if centrate is

conveyed to a rising drain pipe without pump via the skimmer, otherwise main
bearings may be flooded by return flow of the head of liquid to the skimmer.

2.2 Flushing skimmer chamber via centrate line

- at 1/2 speed (1st motor step or with rotor slowing down)
introduce water until it flows over at the solids discharge side

Lubrication instruction 3.2/1-1

Oil-air lubrication

1. Function

Both main bearings are supplied by a separate oil-air-lubrication system. After expiration
of the adjusted interval, oil is conveyed through the piston pump to the dosing unit and
from there delivered to the steady passing compressed air. Fluid drops are dispersed
streakily by a steady air flow and conveyed to the greasing points. The oil remains in the
friction point, the air escapes almost oilfree outside.

Make sure that the lubrication starts before the centrifuge is
started and only stops after the rotor has come to a

CAUTION

2. Adjustments
Pause time

The interval is adjusted at the switch board.
Set value: see sect. 3.1

Air pressure

Adjust air pressure at the control valve (3) to 4.5...5 bar by handwheel.

Pressure switch "Air"

Adjust limit value at the pressure switch (6) to 4 bar with
adjusting screw on the top side.

Pressure switch "Oil"

The limit value at the pressure switch (7) is pre-adjusted to 13 bar.

Air flow

Always turn in adjusting screws on the top of the distributor (5)
completely (=minimum air quantity)

3. First commissioning

1. Control correct laying of feed lines and return lines.

2. Connect compressed air at the valve (2).

3. Adjust air pressure at the control valve (4) to 4.5...5 bar.

4. Fill tank with oil up to “MAX”.

5. Remove greasing lines at the bearing blocks.

6. Control pause time adjustment.

7. Release lubrication (centrifuge must not yet start).

8. Vent the dosing unit:

- Open upper screw (1), actuate pressure switch (9) shortly one time and collect
leaking oil, turn in screw (1).

- Loosen threaded pin (hexagon socket 2mm) at the bottom of the dosing unit (5)
for one turn, actuate pressure switch (9) approx.15 seconds and collect leaking
oil, turn in threaded pin. The threaded pin is located in the center of the screw,
which is marked with figure 10.

Repeat this procedure for each lubricating line.

9. Activate pressure switch (9) several times by hand until oil emerges at the end of
the greasing lines (control with palm, palm must feel oily).

10. Connect lubricating lines at the bearing blocks.

11. Activate pressure switch (9) several times by hand, until oil appears in the return
lines. Control if the air from the collecting tank can exhaust unhindered. (Not
applicable with decanter type Z 73)

12. Functional control at the pressure switch (6+7): reduce air pressure at the control
valve below 4 bar until the fault signal for "air pressure missing" and "oil pressure
missing" appears at the switch board; Adjust air pressure according to step 3.

13. Functional control oil level switch (8): Loosen fixing screws; Pull out level switch until
fault signal appears at the switch board; Install level switch again.

14. When the centrifuge is stopped, pay attention that the lubrication aggregate remains
switched on until the rotor is at standstill!
