Data sheet - The #KSD from KRAFFT Walzen 

KRAFFT #KSD - the largest steel drying cylinder in the world

"... the drying cylinder, from the #KSD series (KRAFFT Steel Dryer), was ordered by Palm mill at Valmet to replace a cast iron cylinder installed in 2002 planned, during the annual shutdown. The steel shell was produced by the company Eisenbau Krämer (EBK). Tolerances and interfaces were defined in close coordination between the houses, thus laying the foundation for subsequent processing at EBK. KRAFFT has chosen the design form named "J2B" with project definition..."

The dimensions of the #KSD are:

  • Diameter 1.830 mm
  • Face length 11.150 mm
  • Design speed 1.800 m/min
