30T Duplex Paper Board Machine

The drying part of duplex paper board machine is a very critical part of the paper production process. Its function is to quickly evaporate the moisture in the wet paper through heat energy transfer, so that the paper reaches the required humidity and quality requirements.

The wet paper undergoes the action of heat energy in the drying part of the duplex paper board machine, and the water evaporates quickly, making the paper dry quickly. This helps improve production efficiency and shorten the paper manufacturing cycle. This article will explain the drying part of duplex paper board machine in more detail.
