ABSTRACT:
An apparatus and process is disclosed for treating bulk material in batches in a container having a revolving shovel mechanism rotatably mounted therein and ball-like striking elements moved by the shovel mechanism, wherein heat is supplied to or removed from the bulk material and/or the bulk material is dried and the striking elements are added to the bulk material for the duration of the treatment. The ball-like striking elements having a substantially higher specific gravity than the bulk material and a diameter of at least twice the smallest distance between the shovel tools of the shovel mechanism and the container wall. The shovel tools each having a forwardly extending portion which is curved. The curved portion imparts a resultant of tangential and radial motions to the ball striking elements when contacted thereby.
