Abstract: 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 sifting 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.

Abstract: The present invention relates to a portable screening and stockpiling apparatus comprising a tracked chassis; a feed system mounted to the chassis for accepting material to be screened; means for moving the feed system upwards from a substantially horizontal transport position with respect to the chassis to an inclined working position at an angle to the chassis and from the inclined position downwards to the substantially horizontal position; a screen box supported on the chassis for accepting material from the feed system, wherein the screen box comprises a first deck for screening any material fed thereinto, whereby material of relatively finer and coarser fractions is adapted respectively to pass through the first deck and across the top of the first deck, a first folding conveyor mounted on the chassis beneath the screen box and feed system to receive fines material passing through the deck of the screen box and to convey same away from a first end of the apparatus; and a second folding conveyor mounted on the chassis and associated with the screen box to receive the coarser material from the top of the deck and to convey same away from a second, opposing end of the apparatus.

Abstract: Vibratory screening machines that include stacked screening deck assemblies are provided. In some embodiments, at least one of the vibratory screening machines can include an outer frame, an inner frame connected to the outer frame, and a vibratory motor assembly secured to the inner frame for vibrating the inner frame. A plurality of screen deck assemblies can be attached to the inner frame in a stacked arrangement, each configured to receive replaceable screen assemblies. The screen assemblies can be secured to respective ones of the plurality of the screen deck assemblies by tensioning the screen assemblies in a direction that a material to be screened flows across the screen assemblies. An undersized material discharge assembly can be configured to receive materials that pass through the screen assemblies, and an oversized material discharge assembly can be configured to receive materials that pass over the screen assemblies.
