Abstract
A dryer for drying material carried along and dried by hot gases including a hollow rotatable drying drum with an inlet and a discharge end, means for driving the drum in rotation and a group of flights projecting into the gas flow stream to break up the material and retard the speed of flow of the material with the flowing gases with the flights arranged in one group at the outer periphery inside the drum and the other supported on a central axially extending core member arranged on the ends of arms projecting radially from the core member to provide satellite groups which are adjustable in a radial rotational and axial directions to change their location relative to the gas flow.
