A vibratory screen assembly with improved structural bracing having a vibratory screen deck defined by pairs of side and end walls that are arranged in a rectangular configuration. Cross members are spaced along the length of the screen deck in parallel relationship with each other and extend between the side walls of the screen deck. Bracing components are mounted exclusively between adjacent pairs of cross members and increase the flexural frequency of the vibratory screen deck. Each bracing component includes a main segment configured to extend between adjacent cross members and end sections formed at each end of the main segment. The end sections are angled with respect to the main segment and are configured to mount to the cross members to brace the screen deck.

A sieve bend can include a support structure supporting a screening arrangement. The screening arrangement can include a first screening segment having a first screening element configuration and at least one further screening segment having a second screening element configuration different from the first screening element configuration.

This disclosure relates to a system and device for cleaning impurities, garbage, rocks and etc. from sand. In one embodiment, a sand cleaning device includes a spinning brush head that includes one or more flaps that push sand through a screen while retaining impurities, garbage, and rocks within a receptacle. The system includes a remote power unit for powering the sand cleaning device.

A scalping insert includes a scalping surface having a plurality of scalping slots therethrough, and a vertical base portion. A shaker screen assembly includes a screen frame having at least one slot. A scalping insert is positioned in the at least one slot of the screen frame. Processing fluid using a shaker screen assembly includes providing a flow of fluid to the shaker screen assembly and flowing the fluid through both a scalping surface and a screen surface of a single shaker screen deck.

The invention concerns a sieve device 10 for use in a device 1 for generative manufacture of components 2 by means of successive solidification of individual layers 3 of powdered solidifiable construction material 4 by exposure to radiation, in particular laser radiation 5, through sector by sector melting or fusing and binding of the construction material 4, comprising a coating device 6 for application of the layers 3 on a carrier 7, a dosing device 8 for preparing the powdered construction material 4 for the coating device 6, an overflow container 9 for receipt of construction material 4 not needed in the coating process that can be fed to the sieve device 10 for sieving the powder material into the overflow container 9 during the construction process, wherein a sieve 12 of the sieve device 10 is configured at least in sections to be inclined in a way that the construction material 4 after appearance on the sieve to be sieved is first brought across the surface of the sieve with an initial velocity and then the transport velocity of the construction material 4 slows or is reduced to a lower velocity over the surface of the sieve.

A process. The process includes forming a slurry comprising electrode active material particles of one or more lithium-ion electrochemical cells, magnetizing the electrode active material particles and separating the magnetized electrode active material particles from the slurry.

A screen assembly for a vibrating shaker is provided. The screen assembly utilizes an elastomeric gasket having a flat profile section and a bulb profile section, wherein said bulb profile section has a hollow interior and is configured so as to form a notched profile section where said bulb profile section connects to said flat profile section.

A metal mesh has a plurality of through-holes. A photosensitive organic material is attached to at least part of the metal mesh. The metal mesh is sterilized and/or cleaned. A determination of whether or not the sterilization and/or cleaning has been successful is made by analyzing the photosensitive organic material attached to the metal mesh.

A screen includes a support structure. A plurality of screening elements is arranged in spaced relationship on the support structure to define screening apertures between adjacent screening elements. Each screening element defines a screening surface, respectively. The screening surface of each of at least some of the screening elements are spaced further from the support structure than the screening surface of each of the remaining screening elements so that, on opposed sides of each screening aperture associated with the at least some of the screening elements, the screening surfaces are at different heights.

A vibratory screening machine includes replaceable screen assemblies. Compression mechanisms are used to secure replaceable screen assemblies to the vibratory screening machine. Each compression mechanism applies a force to a replaceable screen assembly that includes both a horizontal component and a downward vertical component. Each replaceable screen assembly is typically substantially flat prior to installation on a vibratory screening machine. The force applied to a screen assembly by one or more compression mechanisms causes the screen assembly to be pushed into engagement with underlying concave support members such that the screen assembly itself assumes a concave shape with the center of the screen assembly being lower than the side edges. The vertical downward component of the force helps to secure the screen assembly to the screening machine.
