摘要： A screening system having a resiliently mounted housing with a screen extending thereacross. The housing is vibrated by a low frequency vibratory drive using eccentric weights. About the peripheral frame of the screen, a high frequency drive or drives is employed to vibrate the screen in the range of 20,000 Hz. The high frequency vibration is generated at the peripheral frame about the screen. The screen may be responsive to the high frequency vibrations in a plate-like manner or as a membrane. With the high frequency drives mounted within the housing, a structure made of a sheet extends from a mounting flange inwardly to a mounting ring supporting the screen and the high frequency drives and inwardly to a collecting system including a trough and a central dome. The center of the dome may be fixed to the screen and include a high frequency drive.

摘要： A vibratory screen separator having a resiliently mounted frame with a screen mounting to receive screens for material flow thereacross. Eccentric weight systems are rotationally mounted with effective axes of eccentric force coincident. The weight systems are symmetrical about a center plane through the separator for uniform vibration thereacross. The coincident axes extend through the center of gravity. A drive is coupled with both weight systems such that the direction of rotation of the weight systems are opposite to one another in one embodiment and opposite in another.

摘要： Screen assemblies having a plurality of supports assembled with peripheral screen frames with screen cloth extending fully over the assemblies. The supports are assembled with each other and with the screen frame using dovetail mechanisms. Each support includes a cell structure having walls defining open cells. The walls have an elongate cross section to provide thickness to the structure. A thin support grid is integrally formed with the walls with the top of the support grid and the top of the walls lying in the same plane. The top of the surrounding frame also lies in this plane. The walls and the frame each have energy directors for ultrasonic bonding to the screen cloth laid over the assembly. The lower edge of the walls and of the screen frame also lie within a plane and have energy directors for receipt of a larger mesh closure screen to retain self-cleaning sliders or elements within the cells. The cells have no straight edges in plan. The support grid is defined by elongate elements each having a rounded upper surface to reduce stress on the screen cloth. The screen cloth may be lightly tensioned and can be of polymeric material as well as of metal such as stainless.

摘要： A system for providing a self-cleaning function to rectangular vibratory screens which may be disposed on an incline in a vibratory separating system. Pans or screens defining flow-through support surfaces span across the frame of a screen parallel and displaced from the screen cloth. Sliders are positioned on the pans which have the capability of impacting the underside of the screen cloth when the vibratory system is in motion. Dynamic mechanisms for imparting circulatory motion to the sliders include mounting rods associated with the pans or screen frame members which extend laterally across same. Tubes capable of eccentric motion about the rods are mounted thereto such that the vibratory motion of the screening mechanism induces such movement for impacting against sliders to cause slider circulation. The sides of the pans are slightly flared outwardly to engage the screen frame for proper location of the system within each screen.

摘要： A screen assembly, the process for its manufacture, the apparatus used in the process and an adhesive presenting a system and the final product for accurately tensioned bonded screens. The screens include a screen frame and screen cloth bonded thereto by adhesive using bisphenol F epoxy resin, amine adduct hardener, a substantial percentage of amorphous silica and small amounts of glycerin and fumed or precipitated silicon dioxide. Titanium dioxide may also be employed for color. A screen assembly apparatus includes a screen cloth tensioning frame and a platform positionable adjacent a tensioned screen cloth. The platform includes heating elements about the periphery of a sheet heater on a left table. The heating elements receive a screen frame which can be lifted into contact with a screen cloth in the tensioning frame. The sheet heater approaches the screen cloth itself. A thermal control cycle is presented which allows the screen frame to cool prior to the tensioned screen. Blowers enhance the cooling process of the screen frame. Resilient devices are provided to maintain tension in the screen cloth irrespective of heat expansion and to maintain a uniform pressure of the peripheral heating elements against the screen frame and in turn against the screen cloth.

摘要： A system and method allow for the installation and removal of curved screen elements from a shaker table. Pneumatic cylinders are used to move hold down bars either up to allow for screen elements to be installed or removed from the screen bed section assembly, or down to clamp screen elements into the screen bed section assembly of a shaker so that the screen elements will not move during shaker operations. Each curved screen element may have a different radius. Self-adjusting hold down bars compensate for adjacent screen elements having edges that are parallel but at different elevations. The self-adjusting hold down bars also compensate for adjacent screen elements having edges that are not parallel.

摘要： This invention relates to a method for easy installation and removal of a screen assembly for vibratory machinery and more particularly to shake table screening. The screen assembly comprises a screen frame, a screen cloth and a screen bed, whereby no clamping components are visible on top of the screen. Each assembly section can be controlled independently and clamping force is controlled by a pneumatic regulator located near an air line connection on the side of a shaker.
