A method and equipment for reprocessing loose materials, in particular for reprocessing fragment-type fractions and/or free-flowing materials, is proposed, the loose materials arising as fractions or free-flowing sand being reprocessed by the method and the equipment to give a re-utilisable quality approximately as new. The plant (50) designed for wet treatment comprises essentially a washing vessel (10) which is interactively connected via at least two sonic transducers (16, 17) to a correspondingly associated ultrasonic device (15). For the thermal treatment, a drum-type furnace (20) with a heatable combustion chamber (21') is also provided in which a piping system (40) mounted for rotation about its longitudinal axis (X) in the direction of the arrow (Z) is provided, from which the indirectly heated loose material is fed to a first chamber (26) for separating off residual gases and fines. The first chamber (26) is connected via a screen (23) to a second chamber (24), which is subjected to a gaseous medium from a fan (25), the gases and fines being thereby separated from the sand. The gases and fines can be fed via a filter device (22) and return line (27) to the combustion chamber (21').
