Study figure 1 on page 6 - Material flow 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 specified. 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 outflow of solid particles, the liquid content of the material
and the level of vibration. By considering the above mentioned factors and
observing modifications 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 qualified
personnel using only original Nederman spare parts. Contact your nearest
authorized distributor or Nederman for advice on technical service.
