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.

Sieve cleaners (1) for cleaning a sieve surface (2) of a sieve box (3), which sieve box contains a sieve surface (2) and bottom (4). The sieve cleaners (1) contain a wobble foot (5), which extends along a main axis (A) of the sieve cleaner (1) and is designed such that the wobble foot can be placed onto the sieve bottom (4) and the sieve cleaner (1) can be tipped about the wobble foot (5). At least one cleaning element (6) has a cleaning region (7), and each cleaning region (7) has a plurality of cleaning surfaces (8) for cleaning the sieve surface (2). The cleaning surfaces (8) are each designed for at least linear contact with the sieve surface (2) and are separated from one another by slots (9) formed in the cleaning region (7). Sieve units and methods for upgrading or converting a sieve box are also disclosed.

Deblinding apparatuses and deblinding methods are provided. A deblinding apparatus may include a support frame including a grid structure and multiple compartments. Multiple compartments may be formed by a respective portion of the grid structure and a respective set of support members. Further, multiple scattering members may be disposed within a compartment. Scattering members be removably affixed to a portion of the grid structure that forms a part of a compartment. Multiple unsecured objects may be placed within a compartment. When attached to a screen and in response to movement of support frame, at least one unsecured object of the multiple unsecured objects may collide with a first scattering member and with a surface of the screen to thereby cause deblinding of the screen. Sizes, shapes, masses, and morphologies of unsecured objects may be designed to optimize collision rates of unsecured objects with scattering members and with the screen assembly.

A resin tapping member used for a method of separating and recovering that enables a polymer to be separated and recovered from a polymer-containing liquid during or after a polymerization reaction at a high quality, high efficiency, and high processing capacity. The resin tapping member for preventing clogging of a screen is used in separating and recovering a polymer obtained by a polymerization reaction in a solvent. The resin tapping member has a weight reduction percentage of 3 wt. % or less after continuous separating and recovering of a polymer from a polymer-containing liquid for 48 hours.
