Detailed introduction
Yankee dryer cylinder is the core component of household paper equipment.It needs to maintain a stable surface for wrinkling, withstand high intensity wrinkling and clean scraper work, and cope with the occasional idling situation. Optimized thermal spraying coatings, also known as Yanker metallization, are compatible with strippers and prevent jarring.It is used in drying part of a paper production line. Working with hot steam from steam boiler, dryer cylinder dry wet paper sheets, then the dry paper sheets can be reeled into jumbo rolls. Usually, more than 10 dryer cylinders is needed for a paper making machine. Specific quantity varies up to practical conditions of customers.The dryer cylinder is used as a key component for paper drying .
The saturated steam introduced from the steam joint condenses inside the dryer, and the released heat causes the temperature of the dryer to rise, thereby heating the sheet coated on the surface of the roll shell. Heat is transferred to the paper during contact between the paper and the dryer surface. The steam releases heat and condenses to produce a large amount of condensed water, which is discharged.
