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%
The structural composition of the press section of different paper machines is different, but the basic composition is roughly similar.The various devices and components included in the press section of a paper machine can be divided into the following parts
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.
Now the paper industry has basically realized automatic mechanical production. For different paper types, many different types of paper machines have appeared. So what are the precautions for the installation and commissioning of paper machines?
Any papermaking equipment, such as a paper machine, will produce a lot of waste residues during use. The emergence of these papermaking waste residues is owned by every manufacturer. If the manufacturer irresponsibly treats the waste residues directly as garbage, it will cause great damage to the environment.
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
