sludge rotary drum dryer and its working principle in norway

  • Sludge Rotary Drum Dryer and Its Working Principle

    2020-5-16 · The rotary dryer’s drum is a slightly angled and rotatable cylinder with wet material entering from one end up and dry material collecting from the other end down. Hot air enters at the inlet or outlet end and exits at the top of the other end. The barrel is equipped with a forward-running plate, which makes the material to be continuously run up and down in the process of turning the barrel ...

  • Rotary dryer working principle and specifications-Palet

    Drum drying: in drum drying, the heated surface is the envelope of a rotating horizontal metal cylinder. The cylinder is heated by steam condensing inside, at a pressure in the range of 200 to 500 kPa bringing the temperature of the cylinder wall to 120–155°C.The wet material is applied on the drum surface as a relatively thin layer by a variety of different methods to be described later.
