A sieve is disclosed for use in a plansifter. The sieve can be changed between backwire and combined sieve configurations without the height of the sieve changing, and while maintaining contact between a frame of the sieve and the sieve box. A dynamic combined cleaner also is disclosed in which the center of gravity of the cleaner dynamically changes based on inertial movements applied to the cleaner.

This disclosure discloses a shaker screen. The shaker screen comprises a frame and at least one screen layer supported by the frame for sieving materials. The frame comprises a rectangular outer support structure, at least one lateral inner support member, and at least one longitudinal inner support member. The lateral inner support member comprises an aperture, and the longitudinal inner support member comprises a groove on a side of the longitudinal inner support member. The lateral inner support member is engaged with the longitudinal inner support member by engaging the aperture on the lateral inner support member and the groove on the longitudinal inner support member.

A chip sorting screen utilizing a plurality of shaped wire elements sized and spaced to allow for efficient sorting of wood chips and fiber elements. The chip sorting screen includes an upper surface formed of shaped wire elements arranged in parallel relationship to define slots between adjacent shaped wire elements. Each shaped wire element is mounted to a support member 10 define an upper surface. The mounting orientation of the shaped ware element to the support members can be consistent along a screen length or alternatively, the mounting orientation can change along the screen length to selectively vary sorting performance by varying slot size along the sorting screen. A height of each shaped wire element or an angle by which a leading edge of the shaped wire element is presented to the conveying path, can be selectively adjusted to increase wood chip turbulence across the sorting screen.

The present disclosure provides a locking false bottom multifunctional kitchen appliance, including: a main body that is machined into a sheet-like body from a silica gel material, two sides of a left side body and a right side body of the sheet-like body being docked to define a circular body, an upper flange and a lug protruding outwards from a top of the circular body, a support side being disposed at a bottom of the circular body, a groove being recessively disposed on the support side, a docking portion of the circular body being provided with a catch device, the catch device being capable of operating the left side body and the right side body of the circular body for combination or separation. During use, any sheet having a desired number of meshes only needs to be mounted. The sheets are diversified, and thus the product is multifunctional, reasonable in structure, convenient in use, and highly practicable.

A screen assembly for vibratory separation includes a screen having a plurality of raised screen components formed therein, with each of the raised screen components defining a face oriented to oppose a flow direction of the screen assembly. In examples, a screen of the screen assembly is assembled from a plurality of metal cloth layers bonded together. Bonding of the metal cloth layers may be accomplished by a sintering process.

Screening media to screen oversized material includes a main body and a plurality of openings extending through the main body between an upward facing contact face and a downward facing bottom face. A textured pattern is provided at the contact face to provide a roughened surface for the partial entrapment of material fines. Such a configuration protects the screen media from aggressive contact with the material to be screened and provides a bedding layer that is maintained by material-on-material attrition during bulk material flow over the media.

The invention relates to a method for increasing the wear resistance of a metal screen cloth made of wire, the method comprising treating a surface of a metal screen cloth by means of a thermochemical surface layer method for increasing the surface hardness and the wear resistance of metals, wherein the thermochemical surface layer method changes the structural conditions of the treated metal to a predetermined depth of penetration, wherein a hard surface layer is formed in the metal surface. A corresponding device and a screen cloth and a screen panel with increased wear resistance are also part of the invention.
