OPERATING AND MAINTENANCE INSTRUCTIONS MINICOLOR

Operation
MINICOLOR
M SET = Dosing throughput of the dosing station
in kg/h preset nominal value of production
M Batch = Additive per shot in g
t inject = Dosing time in seconds
(preset by the external contact)
3,6 = conversion factor
M Batch x 3,6
Formula 2
t inject
= M SET
Example: i = 30:1
Presumption: Shot weight = 100 g
Masterbatch (or additive share) = 3%
- Additive share in shot = 3 g M Batch
- Dosing time = 5 s t inject
Required: - Dosing throughput in kg/h
Result: = 2,16 kg/h ( use dosing screw type G2)
Example
3 x 3,6
5
= 2,16 kg/h
2. Calibration, determination of calibration quantity: i = 30:1
Given: - Screw type = G2 (throughput 1,4 – 20,0 kg/h)
Required - Dosing
throughput = 2,16 kg/h (from formula 2)
- Motor speed = 110 from performance
scale
- Calibration time = 5 min from performance

Required: - Calibration quantity

− Put MINICOLOR in calibration position
Fig. 5-6
− Put the measuring bucket (1) under the
material outlet
− Fill granulate in the storage bin
− Switch on On/Off switch (3, Fig. 5-4)
switch lights up
dosing screw operates
LED "Motor" (4) lights up
− Allow the dosing screw to run until the
granulate is discharged constantly
the dosing sleeve is now filled with material
− Switch off On/Off switch
switch goes out
dosing screw stops
LED "Motor" (4) goes out
1
− Empty the measuring bucket and put it again
under the material outlet
− Read the calibration time, according to the
dosing throughput, from the performance scale,
Example: 5 min
