As being a key part of the drying system in papermaking, the drying cylinder makes use of high temperature steam to dehydrate and dry incoming papers.
The manufacture process of dryer section mainly includes two types, casting and welding. For the previous one, raw materials are HT200, HT250 and HT300 cast steel and the drying machine is designed with a diameter less than 3660mm. As for welded dryer cylinder, it is most often used for special papers and high-speed tissue paper drying, with a max. diameter of up to 5486mm. Plus, all drying cylinders by Huayi can be electroplated
A drying cylinder mainly consists of a cylinder, end caps, shaft extension and access door. Functional accessories include siphon, bearings, steam rotating joint, gear, gearbox and more.Technical Parameters of Drying Cylinder
