Product Description

Product Description

Dryer Cylinder is divided into: Cast Iron Dryer Cylinder, Steel Dryer Cylinder, Yankee Dryer Cylinder

All dryer cylinders, heads, and journals are special cast iron. Separate journals are bolted onto the dryer heads. Dryer shells are ground on the outside and turned on the inside. All dryer journals with steam or condensate pipes have insulation sleeves. The inner surfaces have grooves for the stationary siphons. The front side ends of all dryers contain manholes.
Cast iron materials are excellent in durability. This is because the free-form flake graphite in the cast iron material ensured its high corrosion and erosion resistance. The cast iron also has good fatigue strength under the pressure roller forces. At the same time, cast iron has good surface performance and does not need metal spraying treatment like a steel dryer.
