pump purge pulse on time
–
the on time of a cleaning pulse to the HDLV transfer pumps in seconds

–
cyclone installed
–
recycle via a cyclone or a different method. When using a different recycling
system, the values below (5 + 6) are used to set a virgin powder mix ratio to realise a consistent amount of
fines within the powder.
5
–
virgin powder mix ratio
–
The virgin ratio is set and the reclaim rate follows correspondingly. e.g. If a
ratio is set for the virgin to be 50%, the reclaim ratio will be 50% as well and both pumps will be on all the
time
If a ratio of 33% is set, the reclaim pump will be on all the time while the virgin pump switches off after 30
seconds. The time base for a pump to run will be 1 minute
(30 sec 60 sec Reclaim = 90 sec powder; where 30 sec is 1/3 rd of 90 sec)
6
–
reclaim powder mix ratio
–
The reclaim ratio is set and the virgin rate follows correspondingly. This will
only be effective if the virgin ratio is larger than the reclaim ration
–
see example above.
