The main body of the paper machine and its auxiliary and auxiliary systems have different forms and specifications. In engineering design, the forms and specifications of various parts are determined based on the types of pulp used in papermaking, paper types, and output requirements.

The commonly used vacuum rolls on paper machines are single-vacuum chambers, but there are also double-chambers and three-chambers.The vacuum degree of the vacuum roller can be used in the range of 46-74kPa. When the top roller covered with a soft rubber layer is installed on the vacuum cover roller

The vacuum roll on the paper machine is mainly dehydrated by vacuum suction. Its advantages are convenient operation, high dehydration rate, less wear of the net, and convenient paper threading. The use of vacuum rolls in the paper machine can increase the dryness of the wet paper to more than 20%

Today with the highly developed science and technology, the final drying of general paper and paperboard is still done by heating and drying with dryers. This is because dryer drying has an ironing effect in addition to the above-mentioned effects. Improve the quality of finished paper.

Reducing the production and maintenance costs of paper machine equipment can improve the production efficiency of the manufacturer, enhance the profit, and better survive in the increasingly fierce market. The operation of the paper machine is not complicated
