Valmet Introduces Sustainable Low-friction Doctor Blades to Reduce Energy Consumption at the Dryer Section of Board and Paper Machines

Valmet is introducing new low-friction doctor blades to respond to customers’ energy savings and decreased doctor blade usage sustainability requirements. The new low-friction doctor blades are suitable for dryer sections in all paper and board machines regardless of the original equipment manufacturer. 

The new doctor blades are made of epoxy resin with glass and/or carbon glass fibre reinforcements. Special attention in research and development was paid to functional fillers for low friction. 

Valmet has conducted a series of successful customer trials with the new blades. “Based on the data given to us by a European customer, the new doctor blades decreased the absolute electric consumption of dryer section electric motors by more than 26 per cent. This results in annual energy savings that are as much as 950 MWh at that mill. When it comes to CO2 emissions, the reduction is 190 tonnes per year,” said Viitasalo.

Valmet’s doctoring offering includes a complete portfolio of doctor blades, holders and other accessories.
