The development status and future development trend of papermaking machinery in recent years have shown rapid growth, which has caused overcapacity to a certain extent, and the industry has encountered greater difficulties. Facts show that the extensive development mode has come to an end, and realizing the strategic transformation of the paper industry is an inevitable requirement for the industry to develop to the current stage. Therefore, adjusting the structure of the paper industry and realizing industry revitalization in the process of adjustment will be a necessary factor for the survival of enterprises in the harsh environment of the financial crisis.

The dryness of the wet paper out of the press section is generally only 30%~40%. In the new paper machine with compound press, the dryness is only 40%~50%. Therefore, it is necessary to use the drying cylinder to evaporate the water to make the paper dry. increased to 92%~95%.

The headbox is known as the "heart" of the paper machine. It is the key component of the paper machine. The function of the headbox in papermaking is to send the pulp that meets the requirements to the forming wire according to the requirements of the forming part of the paper machine, so as to provide the necessary prerequisite for the good forming of the paper web.

Several factors of the formation of paper industry in the papermaking process of papermaking machinery and equipment

The papermaking machine needs to carry out pulp bleaching in the production process. The pulp bleaching process is available in the papermaking machine production line and is also indispensable.The purpose of 　　 pulp bleaching in the paper machine is to remove the lignin and pigment remaining in the
