    batch rotary dryer commonly used in everyday life? 1. Continuous Dryer Design The simpler manner to do the material and enthalpy balances in dryer design is to use a dry basis for both the solids and the hot gas streams. This means that the flows are expressed in mass rates of dry solids and dry gas and the compositions in mass of

    Rotary Dryer Working Principle, Design,Drying System , Uses

    Rotary dryers work by tumbling and drying material in a rotating drum.The wet material enters the dryer from the front end, and when it passes inside the rotating cylinder, it is dried by effective contact with the hot air passing through the cylinder or the heated wall. The dried product is collected from the lower rear end of the cylinder
