Suction rolls provide high performance on all types of pulp drying machines. Aside from rolls for Valmet machinery, we can also offer appropriate spare rolls for a number of other makes. Many of our latest roll technology innovations can be adapted into spare rolls that are compatible with existing rolls. This is an easy and cost-effective way to improve suction roll performance.
Suction roll shells are made of the highest quality Duplex stainless steel shell blanks manufactures through a plate hot rolling or centrifugal casting process. Precision drilling ensures extremely accurate hole positioning and superior hole surface smoothness.
Services for suction rolls include:
Deflection-compensated rolls provide reliable and stable operation. These rolls are the key elements for efficient pressing and dewatering.
Services for deflection-compensated rolls include:
The shoe press bottom roll is the key equipment of our pulp drying machine, and it was a restricting factor for our entire mill. Based on the current situation, its performance meets our expectations,” says Yajun Sun (left) Pulp Making and PDM Facility Manager, Juntai Technology.
Well-performing tube rolls are essential for pulp drying line runnability. High reliability and easy repairability in the case of accidents are also important requirements for these rolls. Valmet’s high-precision tube rolls with optional quick change heads were developed to meet these specific demands.
