Batch cooler + MICOMP UNI Type G-CH/C (Part I ... - Michenfelder

Batch cooler + MICOMP UNI Type G-CH/C (Part I -> Overview)
Here you see the schematised representation of the Webac batch type cooler integrated into the process
control system MiPro in connection with the moisture measurement and control system MICOMP UNI Type
G-CH/C. All relevant information of the current batch and its preparation and the parallel trend development
of many process parameters (individually configurable in various ways) are visible online.

Archiving of process data

Batch cooler + MICOMP UNI Type G-CH/C (Part II -> Batch evaluation)
Here you see a batch evaluation generated with MiPro on the basis of saved batch data from the MiPro
archive. From it can be derived how the output moisture can be maintained consistently and the cooling
capacity thus optimally supported, despite high and fluctuating input temperatures, significant differences
in degrees of evaporation and major fluctuations in the cooling and dispensing water quantities.
ANALYSIS:
The development of three important
parameters in the course of two days of
production with the batch cooler is
represented here comprehensibly and
explicably.
The degree of precision with which the
moisture control system reacts to high
and especially to fluctuating used sand
temperatures (red line) in the cooler
inlet and fully automatically corrects the
total water quantity (blue line) in such a
way that the output moisture = actual
moisture (black line) remains constant
within narrow limits is shown very
clearly by the representation.
The fluctuation in this practical example
amounts to merely ±0.05% on either
side of the actual moisture mean value
of 2.14% H2O. The input temperatures
in this period of time fluctuated between
approx. 80-130°C and the total water
quantities between approx. 250-360 L.
SUMMARY:
The output moisture is maintained
constant with a great deal of reliability
and precision. This means that the
value of at least 2% H2O at the cooler
outlet critical for the sand quality in
downstream processes is securely
achieved, while at the same time the
cooling performance of the batch cooler
is optimally supported.
