Power metering application
We have received the price for required amount of equipment and
works, need to prepare CX application
Tromp curve to be checked on Mill 6 & Mills 4+5
Periodic yearly Tromp Curve inspection is planned for March
Electronic ear on second compartment in Mill 6
We have received the commercial proposal for this project
To be considered for Mills 4 +5 electronic ear
We have received the commercial proposal for this project
False air measurements to be checked
This practice needs to be implemented
Auto stop function to be considered for Mill 6 and to be
installed before year end (share the knowledge from
Pod)
We have received the commercial proposal for this project
Energy saving register
Were created energy saving register and set the periodic quarterly
meetings

Energy reduction
- kWh/t
Heating
optimisation
Change electrical heating to gas heating
0.07
System of auto
operation for the
CM6 installation
Installation FLS PXP system – PXP was implemented in the
beginning of this year , so calculations regarding energy reduction
based on 4 months of stable work with PXP system. To have more
accurate reduction value it’s necessary to repeat this calculations
after few months

Partly done lighting optimisation (changed 211 sources of lighting to
LED)
