A method for disposing of a mixture of oxidizable catalyst material and inert support media. The method comprises introducing inert gas into an enclosure. The enclosure contains a plurality of stacked screens, the stacked screens have openings that decrease in size from a top of the stack to a bottom of the stack. The method also comprises introducing the mixture to an uppermost one of the plurality of stacked screens; moving the plurality of stacked screens to cause the oxidizable catalyst material to separate from and migrate to a location beneath the inert support media; conveying the separated inert support media to a location outside the enclosure for disposal as non-hazardous waste; and conveying the separated oxidizable catalyst material to a location outside the enclosure for at least one of reclamation, or thermal destruction.

A base supports an inclined screen having a uniform mesh selected to remove larger aggregate from a first cement mixture to form a second cement mixture that passes through the screen. A powered vibrator vibrates the screen to separate the concrete mixtures and larger aggregate. Springs and/or dampers in support legs isolate the vibrating screen from the base. A guide frame on the top surface of the screen guides the first concrete mixture along the screen and guide the separated aggregate out a bottom opening into an aggregate container. A support frame on the bottom surface of the screen stiffens the screen to help support the weight of the concrete. A concrete container, preferably wheeled, is below the screen to collect the second concrete mixture and move it to its use location.

A screening bucket system for screening debris out of otherwise clean materials. The screening bucket system generally includes a bucket adapted to be connected to a loader. The bucket includes a rear wall, a pair of side walls, and a blade across its front end. A floor of the bucket is hingedly connected at a front end to the side walls by a hinge. The rear end of the floor includes a rod mount to which a lift rod powered by a motor is rotatably connected such that, when the lift rod is raised or lowered, the free end of the floor raises and lowers while the hinged end of the floor rotates about the hinge. A screen may be positioned on the floor such that materials on the screen may be sifted of debris by activating the lift rod to rapidly raise and lower the floor and screen.

[Object] To provide a building material manufacturing apparatus that is suitable for suppressing clogging of a screen that screens a building raw material. [Solution] A building material manufacturing apparatus X1 includes at least a screen part 10 and a cleaning mechanism part 40. The screen part 10 includes at least one screen sheet 12 that has an inclination and that has a screen mesh. The cleaning mechanism part 40 includes a scraping part 40a. When the apparatus operates in a building material manufacturing mode in which a building raw material M is supplied to the screen sheet 12 and the screen sheet 12 is performing a wave motion, the scraping part 40a is separated from the screen sheet 12, and, when the apparatus operates in a cleaning mode in which the building raw material M is not supplied to the screen sheet 12 and the screen sheet 12 is not performing a wave motion, the scraping part 40a rotates in contact with the screen sheet 12.

A vibratory screener includes a screen carrier frame having inner and outer circumferences, a horizontal screen for separation of solid particles within and vertically supported by the frame, one or more vibration motors on the outer circumference of the screen carrier frame and configured to generate vibration perpendicular to the screen, and at least two internal annular disks each having an inner rim and an outer rim. Each internal annular disk is attached to the inner circumference of the frame by its outer rim, the internal annular disks are spaced apart from each other in parallel planes, and an inner sleeve is arranged within the frame. The inner sleeve is attached the inner rims of two of the internal annular disks, where the upper internal annular disk and the inner sleeve provide an unbroken surface and where the lower internal annular disk has openings towards the outside environment.
