Structural featuresThe preheating roller adopts butterfly type head design, which conforms to the national standard of a class of pressure vessels and comes with a pressure vessel certificate. The surface of each roll after precision grinding and hard chromium plating treatment, small surface friction, durable. Electric adjustment of the wrapping Angle, the wrapping Angle can rotate in the 360° range to adjust the paper heating area. Double speed reducer is used to adjust the Angle of the package, with self-locking function.Technical parametersWork width: 1400-2500mm Preheating roller diameter: ￠600-1100mm Angle axis diameter:￠85mm×2 for Angle shaft diameter Steam temperature: 150-200℃ Steam pressure: 0.8-1.3mpa Motor Power: 250W short time (S2) working system
