Stechnical data of rotary drum dryer

Indirectly Heated Rotary Dryers and Calcinersare available for dusty, finely divided materials and low to medium temperature calcining applications. The rotary drum is partially enclosed and externally heated by a series of burners mounted in an insulated stationary chamber or jacket. Alternatively, the products of combustion from an external

    Development of a high-efficiency rotary dryer for sewage

    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

It consists of a large drum (about 9 m long and with an internal diameter of about 2.5 m), set at a slight angle (about 3 ) in order to let the sugar move slowly under gravity from the inlet to the outlet. The average residence time of the sugar in the dryer is about 7 min

    Abstract This paper deals with the problem of fitting a set of data collected on a rotary sugar dryer, by means of a first-principles mathematical model. Owing to the highly constrained structure of the model, it was discovered that the sugar dryer is characterised by two different working conditions: the “standard-mode” (characterised by a non-zero sugar moisture content), and the

    Industrial Dryer Principle The air sucked by the exhaust fan into the dryer gets heated through the heat exchanger; the wet materials inside the rotary dyer drum are turned over and over to change heat with the hot air. Then the moisture of the fabric is vaporized and ejected out from the dryer, so materials can be dried within a short time

    The volume needed for drying different products varies in practice between 10 and 60 m3/t H2O/h. The drum size also depends on the direction of the drying gas flow in relation to the product flow. Both concurrent and countercurrent drum dryers are produced. The countercurrent dryer is more effective and economical because the temperature difference between the drying gas and product stays
