A system for post-print processing of 3D printed parts includes an automated breakout system for separating 3D printed parts from printing media in a tray and a vibratory media cleaning system for removing printing media from the 3D printed parts. The automated breakout system includes a tray input mechanism, a bed including a first end disposed adjacent the tray input mechanism, the bed including one or more passageways configured to pass printing media through the bed, a vibration generator coupled to the bed and configured to vibrate the bed, and a part terminator disposed adjacent a second end of the bed. The vibratory media cleaning system include a vibratory bin, a vibration generator coupled to the vibratory bin and configured to vibrate the vibratory bin, an automated parts loader configured to introduce 3D printed parts to be cleaned into the bin, and an automated parts removal mechanism.

The invention is used in various branches of industry, in particular in agriculture for preparing seeds for sowing and for selection purposes. The method of separating a granular mixture in a flowing medium is based on a gravitational supply of particles, with an aerodynamic, monotonously increasing action thereon with a cascade of flat jets, said cascade being stabilized in terms of pressure and discharge. Large impurities are removed from the granular mixture beforehand, and stable parameters are maintained in the separation chamber. The device comprises a vibrating screen, an adjustable hopper with an agitator and a vibrating chute, a generator of a cascade of flat jets, which is connected to a drive for supplying air under pressure, a fraction collector and a separation chamber. The output of the separation chamber is covered with a filtering element in the form of a rotating drum with a calibrating sifter on the surface, said sifter being connected to a cyclone.

An apparatus for producing a construction material for use in the building industry is disclosed. The apparatus comprises a hopper (10) which includes a trough (11) having a base section and an open top to allow material to be added to the hopper. The base section of the hopper includes a grinding array (24). A separation array (152) is deployed above the open top with the separation array comprising a plurality of elongate tines (151), each having a first end and a second end, mounted parallel to each other, and secured at least at one end to a support means.

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.
