MM Kolicevo BM 3: Runnability and efficiency improved with coater section rebuild
Jul 6, 2017
All the targets for the coater section rebuild project were achieved at the Mayr-Melnhof Kolicevo mill in Slovenia. Coating quality, runnability and efficiency were improved. A multilayer curtain coating station and a blade coating station started up at the board machine 3 (BM 3) after a very short shutdown period in the summer of 2015. A supply system for the two curtain coating layers was also installed. Before the rebuild decision was made, the coating concept, coating color chemistry, and performance were tested at Valmet's Paper Technology Center in Finland.
Summary
Location | Mayr-Melnhof Kolicevo mill in Kolicevo, Slovenia |
Customer challenge |
Challenges with runnability and efficiency. Coater technology not suitable for increased speed. |
Solution |
Pilot trials at Valmet Technology Center prior to investment decision. Coater section rebuild with:
|
Results |
After start-up the board was sellable in ten minutes. The coating section has been easy to operate and more reliable since the rebuild. Curtain coating has a contactless coating application, which is good for runnability and reduces web breaks. There is less second-rate board and fewer breaks at the coating section. Also, the day-to-day handling is a lot easier than before. |
