A screening system is disclosed. The screening system includes a frame and a screen assembly disposed within the frame. The screen assembly includes a screen and a screen tensioning assembly. The screen tensioning assembly includes a hub defining a through bore centrally disposed on the hub, a rod coupled to the hub and disposed in the through bore, a plurality of support arms, a support ring, and a tensioner. The tensioner adjustably controls a tension state of the screen.
A screen basket includes a first screen retainer for securing a first end of a tubular screen. A plurality of rods are arranged around a perimeter of the screen basket and are secured to the first screen retainer. Each of the rods includes a threaded section spaced from the first screen retainer. The screen basket also includes a second screen retainer having a second support ring for securing a second end of the tubular screen. The second screen retainer is adjustably mounted on the plurality of rods at a distance from the first screen retainer. The screen basket also includes a plurality of elongated sleeve nuts respectively disposed on the rods for holding the second screen retainer in a tensioned position. Each sleeve nut is sized and configured to enclose the threaded section of the respective rod when the second retainer is in the tensioned position.
B07B 13/11 - Grading or sorting solid materials by dry methods, not otherwise provided forSorting articles otherwise than by indirectly controlled devices using momentum effects involving travel of particles over surfaces which separate by centrifugal force or by relative friction between particles and such surfaces, e.g. helical sorters

DUAL DECK FLUID BED PROCESSOR WITH SEPARATE AIR FLOWS
A vibrating fluid bed dryer includes a first dryer stage including a first fluid bed air distribution plate mounted therein, and also includes a first air inlet. A a second dryer stage that includes a second fluid bed air distribution plate mounted therein is positioned to receive material from the first dryer stage. The second dryer stage includes a second air inlet. A drive assembly is coupled to vibrate the first dryer stage and the second dryer stage. The first dryer stage may be coupled to a source of cooling air and the second dryer stage may be coupled to a source of warming air, or vice-versa, or both dryer stages may be coupled to a source or warming air or cooling air.
F26B 3/092 - Drying solid materials or objects by processes involving the application of heat by convection, i.e. heat being conveyed from a heat source to the materials or objects to be dried by a gas or vapour, e.g. air the gas or vapour flowing through the materials or objects to be dried so as to loosen them, e.g. to form a fluidised bed agitating the fluidised bed, e.g. by vibrating or pulsating
A vibratory screener apparatus has a housing with upper and lower ends, the lower end having a first mounting area characterized by a first attachment diameter. A drive assembly is employed to vibrate the apparatus. The drive assembly has a second mounting area characterized by a second attachment diameter to mount the frame to the drive assembly. An adapter frame is disposed between the drive assembly and the lower end of the housing. The adapter frame has a first end and a second end, the first end is characterized by the first attachment diameter and is attached to the lower end of the housing. The second end is characterized by the second attachment diameter and attached is to the drive assembly.
