: A process and an apparatus for the preparation of bulk materials, especially for the preparation of fragmentary fractions and/or pourable materials are proposed, by means of which the bulk material can be prepared to assume a quality of substantially new value. The apparatus (100) comprises a first washing vessel (30), a second washing vessel (40) as well as a drum-type furnace (220) which is connected to this via a line (14) and in which is arranged an externally heatable pipeline system (240) rotatable about its longitudinal axis (X). The bulk material is fed largely in free fall to the first washing vessel (30), is thereby subjected by a number of nozzles arranged in the interior to a highpressure liquid medium and is subsequently cleaned and separated in the second washing vessel (40), whilst the cleaned bulk material is dried and thereafter guided for thermal treatment through the heated pipeline system (240).
