triple shell rotary drying kiln

triple shell rotary drying kiln

The appearance of the rotary drum is no different from that of a normal rotary drum dryer, but the interior is a set of three straight drums of varying diameters, forming a three-ring drum, with a cross-plate on all surfaces where it comes into contact with the material.The three layers of rollers are radially fixed to each other and rotate at the same number of revolutions

    Rotary Kilns vs. Rotary Dryers: What’s the Difference?

    Rotary kilns are designed to withstand much higher temperatures than a rotary dryer. Typically, if you are dealing with a direct fired rotary kiln, it is refractory lined with a brick or castable lining. This lining protects the steel shell. Rotary dryers are typically not lined, and their steel is not able to withstand such high temperatures
