Abstract
Apparatus for drying or cooling bulk material of the type which includes a vibratory conveyor through which the bulk material is transported includes the improvement wherein a plurality of partition members are provided in the conveyor so as to define between them a plurality of channels, the partition members preferably having fin-tube configurations whereby the same carry a thermal transfer fluid for facilitating the heat treatment of the bulk material. Apparatus for screening the fine portion of the bulk material is provided in the channels which preferably narrow in the direction in which the bulk material is transported so that the fine portion of the material receives less thermal treatment.
