A method for treating a contaminated metal powder obtained as a residue of a metal deposition process is provided. The method includes receiving, by a vibratory filtering apparatus, the contaminated metal powder generated during the metal deposition process. The contaminated metal powder is received from a top end of the vibratory filtering apparatus. The method further includes filtering the contaminated metal powder by passing the contaminated metal powder through a plurality of filter plates. The plurality of filter plates are so positioned sequentially along a height of the vibratory filtering apparatus that dimensions of a first plurality of holes of a filter plate are larger than dimensions of a second plurality of holes of a subsequent filter plate placed below. The vibratory filtering apparatus is vibrating during the filtering of the contaminated metal powder. The method further includes obtaining, by a receptacle, a filtered metal powder that is reusable.

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.

The present invention relates to a portable and removable vibration sieving apparatus that sorts plant extract and the like according to size, and more particularly, to a sieving apparatus using motorized vibration that is suitable for sorting plant extracts or other particles.

A method of recycling build material powder including collecting in a keg an amount of excess build material powder during the additive manufacturing of a part cake. The part cake and keg are transferred to a de-powdering station. The part cake is de-powdered to release a mixture of reusable powder and contaminants. The mixture is sieved to remove the contaminants and deposit the reusable powder to the keg.

Devices and methods for improved separation of small particles from other stock. The device includes a sifting tray assembly and means for vibrating the screen of the shifting tray assembly for separating components and a cryogenic fluid source and injection system for freezing the small parts to the point where they are solid enough to pass through the screen without adhering to the screen. The method entails use of the system to separate small particles in sifting trays while spraying the stock with a cryogen such as liquid nitrogen.
