4 Safety
This chapter contains important information that refer to a potential hazard to
the health and safety of personnel, and how that hazard may be avoided.
• Electrical installations have to be done by qualied personnel only.
• At connection of voltage feed as well as at service and maintenance work
on the centrifuge the circuit breaker must be off.
• Test the emergency stop at installation and always when maintenance and
service have been done.
• The centrifuge must not be operated with the covers removed.
• Materials able to centrifuge are different qualities of steel swarf as well as
brass and cast iron swarf, if any other material please ask Nederman.
• The data sheet from the coolant supplier must be studied as parts from
coolant can cause allergic reactions.
WARNING!
The oor around the centrifuge might get slippery from coolant getting
outside the machine.
5 Description
5.1 Function
The NEDERMAN horizontal centrifuge is a drum centrifuge, which via
rotation movement exposes the supplied material to high G-forces. The solid
particles are separated on the inner periphery of a screen, whilst the liquid
passes through this.
Figure 1 shows the material ow through the centrifuge.
The material fed in through the top inlet hopper (1), glides down and is fed
directly to the drum walls (6). On contact with the drum walls the material is
accelerated to the speed of the drum at the periphery. During this acceleration
phase the material moves outwards along the drum until it comes into contact
with the wedge bar screen (3) or remaining layer of previously accelerated
material. By building up an additional layer of material over the previous layer
the old material is forced to glide over the screen and out from the centrifuge
via the outlet for dry chips (4). During the time the material is exposed to the
centrifugal force the liquid is separated from the solid particles. When the
material passes over the screen the liquid goes through this and out from the
centrifuge via the outlet for liquids (7). This outlet is located immediately
behind the outlet for dry chips.
A conveyor should be connected to remove the solid particles. The liquid
should be drained to a sedimentation tank, which in turn should be equipped
with a drag conveyor.
Your NEDERMAN Swarf Centrifuge is designed to operate at high rpm and
is almost completely vibrationless. Each component in the rotating system
is individually balanced so that all parts are fully replaceable without disturbing
overall balance.

HD82EN
14 QMM001(02)
Despite the fact that the parts are individually balanced a certain imbalance
may arise when material is fed in. To avoid vibrations being transferred to
mountings the centrifuge is installed on vibration absorbers.
The screen opening is delivered as a standard 0.7 mm if not otherwise specied
in the order. Other screen openings may be tted.

7 Before installation
7.1 Delivery checks
Check the unit for any transport damage. In case of damage or parts missing,
notify the carrier and your local Nederman representative immediately.
7.2 Installation requirements
Lifting instructions
Lift the centrifuge by crane. Use a 2-part chain of approved quality and
strength and in adapted lengths. Place the chain in the eye bolts on the upper
side of the centrifuge. See Figure 2.
Weight 1400 kg.
8 Installation
8.1 Installing the Swarf Centrifuge
Consideration must be taken to the positioning of the centrifuge in relation
to other equipment. The centrifuge requires very little space. However, space
for maintenance must be available and adequate space must be ensured for
access to all the hatches. There must be space in front of the centrifuge for the
replacement of screen, drum and the interior components.
Lifting xtures should be available in view of the fact that several of the parts
which need to be replaced weigh over 125 kg.
NEDERMAN Swarf Centrifuge is delivered fully tted. Observe care during
installation and always use the lifting hooks which it is equipped with. The
mountings should be level and sufciently secure to support a load of about
1700 kg (incl. frame and outlet chutes) and also be available to sustain dynamic
loads via the centrifuge´s vibration absorber. The dynamic loading is normally
very low.
There should be no rigid connections to the centrifuge. When the centrifuge
is correctly installed it should be able to vibrate on the vibration absorbers
without striking or causing any abrasion against any connection. Liquid and
solid particles should be fed to a tank or conveyor. A xed pipe connection
should be avoided. The liquid outlet, however, must be shielded to prevent
splash.
The motor is dimensioned as 11 kW, 3-phase, 400 V, 50 Hz.
The electric cables to the motor must accommodate a certain exibility.
9 Using Swarf Centrifuge
9.1 Before start-up
NOTE! The centrifuge is designed for approximately 1-5cm long chips. Before
feeding the centrifuge solid parts should be separated to reduce wear and
sound level.

HD82EN
16 QMM001(02)
Study gure 1 on page 6 - Material ow in centrifuge - where a general
description is provided.
Check the following points prior to putting into operation:
1. Free rotation:
The drum should be able to be turned round by hand.
2. Motor loading:
Check power consumption while idle running and compare with power
during loading and rating data of motor.
3. Observation of idle running sound:
Attention should be paid to the normal sound level of the equipment.
NOTE! A screaming noise may be emitted by the V-belt when the drum
is accelerating. This is normal.
4. Always start the centrifuge unloaded:
If the centrifuge is started when loaded then start load will exceed motor
capacity. The centrifuge must not be fed until the correct speed of the
drum has arisen.
5. Feed the centrifuge evenly:
Since the centrifuge works continuously it is of great importance that
it is fed evenly to ensure a level of residual moisture in the centrifuged
chips as low as possible. The feeding of the centrifuge should be done in
intervals by a conveyor. As default setting on the feeding conveyor 4s stop
time is used followed by 2s run time. This value can vary depending on
the shape of the material.
6. Supplementary adjustment:
NEDERMAN Swarf Centrifuge is on delivery adjusted to cope with the
majority of chip types unless otherwise specied. If a chip type should be
run subsequently to installation which was unknown to us on the occasion
of installation then a supplementary adjustment may be made.
9.2 Operation
The operator should always be aware of the normal power consumption of
the motor, normal outow of solid particles, the liquid content of the material
and the level of vibration. By considering the above mentioned factors and
observing modications one can be sure that the centrifuge will function
properly.
NOTE! The centrifuge is designed for about 1-5 cm long chips. The solid
components should be removed before loading the centrifuge, to reduce wear
and noise.
10 Maintenance
Read Chapter ‘4 Safety’ before carrying out maintenance.
Installation, repair and maintenance work is to be carried out by qualied
personnel using only original Nederman spare parts. Contact your nearest
authorized distributor or Nederman for advice on technical service.

HD82
17QMM001(02)
EN
NOTE! The service intervals in this chapter are based on the unit being
professionally maintained.
NEDERMAN Swarf Centrifuge is very robust in design but should like every
other production machine be regularly checked and maintained. Daily checks
should be made at the start of operations until a permanent maintenance
schedule can be established. When this has been done only routine checks and
general observations are necessary.
All parts coming into contact with the material which passes through the
centrifuge are subject to wear. Negligent or delayed replacement of worn
parts results in high repair costs and unsatisfactory separating of liquid.
A maintenance schedule should therefore be established which also indicates
when it is time to replace worn parts. This schedule may only be drawn up by
you since wear is highly dependent upon the ingoing chip quality. A basic rule,
however, is to check the screen, drum and housing once a month in the case of
1-shift operations. Inspection takes place via the front door.
10.1 Lubrication
The Swarf Centrifuge has an automatic lubricator for the two roll bearings.
The lubricator is on delivery lled with oil, Shell OMALA 68 or equivalent.
Check the oil level in the container regularly (once a month) and ll
additionally. Changing of oil must be done every six months during 1-shift
operation.
A grease nipple is situated between the packing rings at the housing.
On delivery LOCTITE 8102 grease or equivalent has been used.
The greasing intervals should be adjusted to the operating intensity, there must
always be grease between the packing rings.
10.2 Spare parts
Contact your nearest authorized distributor or Nederman for advice on
technical service or if you require help with spare parts. See also:
