Efficiency of rotary drun drier

Feb 16, 2012 A rotary drum dryer having an internal rotating body was designed and tested in this study. It was shown that the developed dryer is effective for drying sewage sludge. The best operating conditions in the dryer were low energy input and almost 10% moisture content. The conditions are 255 C for the rotary drum temperature, 17 min for the sludge residence time, and 55 kg/m3 h for the

    Nov 11, 2020 The drying drum is the heart of a rotary dryer, and the place where the drying gas and wet material are brought into contact. The material is showered through the air by rotating the drum. As the drum rotates, lifters mounted on the shell wall carry material up to the top, where it drops as a continuous curtain as the air passes through it

    May 16, 2020 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

    Another study of a combined conduction–convection type rotary drum dryer was made by Regalado and Madamba (1997) on thermal efficiency. The fresh ambient air forced inside the drum in a counter flow direction of grain brought evaporative cooling of the hot grain as shown by the increase in moisture reduction whenever air velocity was increased
