Product Description
Yankee dryer cylinder is a vital component of a paper machine, as it is responsible for drying and smoothing the paper once it has been formed. Yankee dryers are typically made of cast iron or steel and can measure up to 6 meters in diameter and 10 meters in length. This cylinder is coated with a layer of creping adhesive, which creates a crepe-like texture on the paper as it is dried.
Some important parts of a Yankee dryer cylinder include:
1. Shell: The shell is the main body of the cylinder and is responsible for holding the paper in place as it is dried.
2. Head and tail: The head and tail are the two ends of the cylinder and are responsible for sealing the cylinder and allowing for the insertion and removal of steam and condensate.
3. Steam supply headers: These headers provide steam to the cylinder for heating and drying the paper.
4. Condensate removal system: This system removes the condensate that accumulates on the surface of the cylinder during the drying process.
5. Doctor blades: Doctor blades are used to remove any excess adhesive or debris from the surface of the cylinder.
The Yankee dryer cylinder plays a crucial role in the papermaking process, and the proper functioning of its parts is necessary for producing high-quality paper products.
