Hamburger Hungaria was troubled by short running times, an unscheduled downtime and extensive maintenance on its PM 7 pick-up rolls. In 2019, Valmet delivered two oil-lubricated pick-up rolls with a two-suction chamber solution to the mill and the running time of pick-up suction roll more than tripled.
|Location||Hamburger Hungarial mill in Dunaújváros, Hungary
The mill was looking for a solution to extend pick-up suction roll running times by avoiding shell hole plugging and axial seal wearing issues. They had been causing unplanned roll changes every three to four months.
Valmet delivered two oil lubricated pick-up rolls with a two-suction chamber to the mill. The rolls were equipped with:
100 percent waste-based lightweight brown liner and corrugated medium
|Wire width||7,8 m|
