Dryer Cylinder for Paper Mill


The number of cast iron dryers accounts for about 2/3 of the total number of pressure vessels in the paper industry. The material for making the dryer is generally HT200 and HT250. In the manufacture of quality requirements and no penetration and large blisters, in order to increase the smoothness of the paper, the outer surface of the dryer polished inner surface turning light, keep the cylinder wall thickness is consistent, in order to ensure safety, balance and heat evenly throughout the dryer. The dryer is used to dry the paper sheets in the water, surface finishing.
