4.7.1 Change of material
The stop/start procedure applies to change of material also.
At change of material it is recommended to clean out dust and regrind from the hopper.
Remaining granulate can be removed by opening the slide valve. Dust can be removed by
opening the lid or by disassemble the sight glass and clean out using compressed air - the
discharge valve (31) must be kept open during this procedure.
4.8 Stop
1. If attached stop Con-Evator on main switch placed on its control.
2. Discharge the CD drying hopper either by running
it dry or by discharging it through the discharge
valve (31) in the cone of the drying hopper.
It is recommended to leave the CD blower on
during discharging, as it will facilitate discharging.
3. When the drying hopper has run empty, or if it
is required to interrupt production, the CD is
stopped on the main switch (18).
4. At long production stops it is recommended
to lower the temperature to avoid “overdrying”
of the material.
