Audited Supplier The dryer cylinder for paper machine is a key part of paper drying, which is class I pressure vessel. The number of dryer cylinder accounts for about 2 / 3 of the total pressure vessels in the paper industry. Generally, the materials used for drying cylinder are HT200 and HT250. In order to increase the smoothness of paper surface, the outer surface of the dryer should be polished and the inner surface should be polished to keep the thickness of the whole dryer wall consistent, so as to ensure the safety, balance and uniform heat transfer of the dryer. The function of the dryer is to dry the moisture in the paper and finish the paper surface.
1.The shell is thinner,ensure the more heat to transfer(Evaporate rate).
2.Better elasticity,stronger compressive resistance,which have enough security coefficient for heat shock,machinery fault and potential explosion etc hazards.
3.The surface metal spraying adopts advanced foreign technology and equipment,increase service life.4.The metal coating of surface can reinforce the chemical coating and wrinkling.
5.No bolts heads to block,can improve the papers stable performance.
6.During operating,the shell thickness is reduced and the metal coating is fall off,which not affects the using performance.
7.Since the date of installing can be put into operating,don't need to run-in with the host,its performance will not reduce as the service life is growing
The main parts of cylinder dryer include: shell,dryer bars,syphon, manhole cover, shell head, spherical roller bearing, steam joint ,etc.
