<p>PROBLEM TO BE SOLVED: To provide a an apparatus which removes components adherent to solids such as concrete waste as fine powder without pulverizing the solids. SOLUTION: Solids such as concrete waste are put into a drum 2. The drum 2 is rotated at a prescribed speed while the inside of the drum 2 being ventilated. By the rotation of the drum 2, the solids are mixed, agitated, and mashed and kneaded with deformed bars 18. Components which are adhered to and mixed into the solids is made fine powder to be discharged outside the drum by an air flow. The solids after being kneaded pass through wire nets 12, 13, and those not exceeding a given size is discharged separately from the fine powder. The deformed bars 18 are prevented from flying out from the drum 2 by the wire nets 12, 13.</p> |
