Technical parameter: 1.Diameter of pre-heater roller:800mm,900mm,1000mm,1100mm available discretionarily. 2.Effective width:1400-2500mm Characteristics: Cylinder surface grinded and polish treated.The inverter system controls the motor and adjusts the speed of the cylinder, to splice betterr, and especially for the lower quality paper.Foru director rollers(two floating roller electric adjustment, and two fixed roller) heating in direct of almost 360.For the foru director rollers, high pressure when the paper thought the cylinder, it enables a good heating effect even working in low steam pressure,to save energy.The cylinder circumgyrate to enhance the heat.Can be combined into multi-pre-heater(such as double/triple/quadruply per-heater).
