Paper Machine Steel Plated and Cast Iron Dryer Cylinder

Steel Plated and Cast Iron Dryer Cylinder for Paper Machine

After forming and pressing, the paper still has a lot of moisture inside. The paper contacts the dryer cylinder, the core equipment of the drying section, to evaporate its internal moisture and become a dry finished paper. The dryer cylinder can be arranged in a multi cylinder form, and through the continuous drying of multiple dryer cylinder, the paper can quickly achieve the ideal drying effect. (In addition: The quality of the dryer cylinder has an important influence on the quality of the finished paper and the drying effect. A good dryer cylinder should have a smooth surface and uniform wall thickness to ensure uniform heat transfer).

Component of Dryer Cylinder

Journal: The general term for the operating side shaft and transmission side shaft of a dryer. The design and manufacturing process of this dryer are quite complex, requiring high-precision welding and mechanical processing.

Annular stiffening plate: The annular stiffening plate is an important component of the dryer shaft head. It plays a role in distributing the torque of the shaft head by connecting with the reinforcing rib plate, ensuring that the dryer can operate stably and efficiently.

Dryer shell: The important component of a dryer is a cylindrical shell with a cylindrical shape.

Width of dryer: The length of the dryer cylinder surface along the axial direction is an important indicator for measuring the performance of the dryer.

End cover: The structure that seals both ends of the cylinder body.

Yankee Dryer Cylinder

Dryer Cylinder can be divided into ordinary steel dryers and Yankee steel dryers according to their production purposes. The ordinary dryer cylinder is usually used in multi cylinder type paper machines, with an outer diameter generally not exceeding 3000mm; the Yankee dryer is mostly used in paper machines producing thin paper, with an outer diameter usually exceeding 2400mm. The structural type of steel drying cylinders is equally important, mainly divided into centerless shaft structure and centerless shaft structure. Steel ordinary dryers generally adopt a centerless shaft structure, while steel Yankee dryers often adopt a core shaft structure.
