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 sieving system for a powder is provided. The sieving system includes a support structure; a filter housing movable relative to the support structure, the filter housing defining an inlet and an outlet, the filter housing comprising a broad frequency filter disposed between the inlet and the outlet, the broad frequency filter configured to restrict a first portion of the powder larger than a predetermined threshold from reaching the outlet; and a powder mass control assembly configured to determine data indicative of a powder mass within a portion of the sieving system and control one or more operations of the sieving system based on the determined data indicative of the powder mass.

The invention relates to a device for continuously sorting a particulate stream, comprising: a) a screw conveyor (1) for conveying the particulate stream to a separation device, b) a sieve (7) for separating the particulate stream ac cording to size, characterized in that it further comprises c) a pre-sieve (3) comprising elongated sieve openings formed by fingers extending towards an end portion of the pre-sieve with the tips of the fingers not being connected in that end portion, the pre-sieve (3) being located between the conveyor outlet and the sieve, d) wherein the pre-sieve (3) encloses part of the circumference of the conveyor screw in an axial end portion of the conveyor screw, and e) the radial distance between the conveyor screw (1) and the pre-sieve (3) is less than 10%, preferably less than 5% of the conveyor screw diameter. The pre-sieve allows to separate elongated objects like threads or wires from the particulate stream which would otherwise clog or block subsequent separation devices including the sieve.
