Dryer Cylinder is divided
into :Cast Iron Dryer
Cylinder,Steel Dryer Cylinder,Yankee
Dryer Cylinder
All dryer cylinders, heads and journals are
made of 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 material 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 itself has a good surface performance, does
not need metal spraying treatment like steel dryer.
A Yankee dryer cylinder is a pressure vessel used in the production of tissue paper. On the Yankee dryer cylinder, the paper goes from approximately 42-45% dryness to just over 89% dryness. In industry, MG cylinders or Yankee dryers are primarily used to remove excess moisture from pulp that is about to be converted into paper. The Yankee cylinder can be equipped with a doctor blade and sprayed with adhesives to make the paper stick. Creping is done by the Yankee's doctor blade that is scraping the dry paper off the cylinder surface thereby crêping the paper. The crinkle (crêping) is controlled by the strength of the adhesive, geometry of the doctor blade, speed difference between the yankee and final section of the paper machine and paper pulp characteristics.
