Abstract: A solid fuel manufacturing apparatus includes: a mixture producing device to produce a mixture by kneading wet combustible waste and a dehydrating agent to accelerate dehydrating the combustible waste; a mixture containing device; an intake device to introduce outside air into the mixture containing device; an exhaust device to discharge exhaust air out of the mixture containing device; a drive device to rotate the mixture containing device; a control device to control operations of the drive device; and a breaking device to break up the mixture contained in the mixture containing device. The dehydrating agent is made of an emulsion containing synthetic resin. The breaking device is placed along an inner peripheral wall of the mixture containing device and configured to scoop the mixture upward in the internal space and allow the mixture to freely fall from above in the internal space by rotation of the mixture containing device.

Abstract: A material separation device comprises a placement component, a blower, a suction component, a suction pad driver, and a controller. The blower blows air at a plurality of aluminum sheets that have been stacked on the placement component to float an uppermost aluminum sheet. The suction component uses suction pads to chuck and hold the uppermost aluminum sheet from above while the air is being blown. The suction pad driver drives the suction component up and down, using servomotors as a drive source. The controller performs control so that the suction pads chucking the aluminum sheet are raised to a temporary stopping position by the suction pad driver, and the suction pads are stopped for a predetermined length of time at the temporary stopping position while the air is stopped, and the suction pads are then raised by the suction pad drivers to a conveyance position.
