Abstract
The present invention relates to a granulating and coating technique, and more particularly to a technique wherein powder and granules are contained in a drum rotating about a substantially horizontal axis and the rotary drum is rotated for granulation of the granules and (or) coating. There is provided a rotary drum (1) for containing the powder and granules (M) and rotating about the substantially horizontal axis, and also provided a buffle member (12) continuously or intermittently rotating or swinging at the inside of the powder and granules (M) layer in the rotary drum (1). The buffle is turned in the granules, so that the raw materials for the powder and granules can be prevented from adhering to the buffle member and the rotary drum or from peeling off therefrom, thus obtaining products of uniform coating.
