    Things to Consider When Selecting a Rotary Dryer

    Dec 17, 2015 Direct heat rotary dryers pass a stream of drying air through the drum. The drying air is directed in either a co-current flow (flowing the same direction as the material), or counter-current flow (moving in the opposite direction of the material). Direct dryers are the most common choice for drying bulk solids, because they are so efficient
