Description

Efficient combined material lifting device: Based on material changes in physical properties during the drying process, the rotary drum dryer adopts a variety of structural combination of lifting plate. rotary drum dryer is arranged according to different temperature sections to turn the material into a uniform material curtain in the cylinder to reach fully heat exchange with the hot flue gases. Its evaporation capacity in unit volume is ****0kg/Nm3, *****0% higher than common drying machine. (The drying machine saves one-fourth calorific value per kilogram water compared to conventional dryers); Using special designs and methods, the material drying process solves the problem of drying high viscosity material hardly and have a great effect. Servo type self-aligning idler wheel device: Normally, supporting wheel and roller is point-contacting while the Servo type self-aligning idler wheel device makes supporting wheel and roller line-contacting all the time. Run-out tolerance caused by deformation of roll ring installation and cylinder body difference in temperature does not affect the contact quality. Roll ring, supporting wheel and driving gear relatively suffer from less wear and power loss, which increases stability of cylinder operation. Zero horizontal thrust drive: The drive reduces the positive pressure of supporting wheel and the load on it through reduction of its bearing angle. The optimal position of the drive gears makes horizontal thrust zero to reduce the drive power by more than *8% when driving cylinder is rotating. Meanwhile the size of the supporting wheel base significantly reduces and the cylinder operates stably and reliably.
