Record-breaking calender rolls for Papierfabrik Palm mill in UK
N
ew calender rolls – said to be the heaviest of their type in the world – have
been ordered for Papierfabrik Palm newsprint mill at King’s Lynn in the UK. Installation of the rolls that
feature a heating system, replacing two that were supplied by Voith for the mill’s PM7 line ten years ago, will be completed by the end of 2020. The calender rolls are being
cast at Hüttenwerke Königsbronn in the Heidenheim district of Germany. The castings for the rolls have
an external diameter of around 1.6 metres, are more than 11
The calender rolls for Papierfabrik Palm are made from 76-tonne castings
metres long and weigh around 76 tonnes. They are made from ductile cast iron, which enables the finished calender rolls to be heated up to a surface temperature of 210 deg C. “These dimensions make
them the heaviest calender rolls
worldwide made from the modern materials,” says Christian Tenbruck, sales and application chief at Voith. The rolls are induction- hardened during manufacture, giving a higher load capacity, fatigue strength and durability. Collaboration between
