A vibrating screen feed conveying apparatus for conveying and separating sticky “moisture laden bulk solids” which are sticky and wet flowing onto a vibrating screening feeder and into a hopper. The apparatus includes a bed on which material is conveyed, a longitudinal counterbalance supported on a plurality of isolation springs, a plurality of inclined drive springs extending between the bed and the longitudinal counterbalance, and a plurality of stabilizers for controlling movement of the drive springs along their central axes. A plurality of vibratory motors, each having rotatable eccentric weights are attached to the rear end of the longitudinal counterbalance. The eccentric weights rotate in phase with one another to vibrate the bed at a vibration frequency.

In a method for cleaning blinding particles in crushers, material to be crushed is fed via a feed stream (1) to a crushing tool, and from there is separated by a screen (7) into a conveyor stream (8) that passes through the screen (7) and a return stream (10) that is held back by the screen (7) and returned to the feed stream (1), thereby forming a conveyance circuit (9). The method makes an efficient, continuous crusher operation possible, wherein idle times for cleaning blinding particles can be avoided. The particle size distribution and/or the material volume are measured at specified intervals in parts of the conveyance circuit (9) and/or conveyor stream (8), and if the particle size distribution and/or material volume deviate above a predefined limit value, the particle size created by the crushing tool is increased for a predefined time period.

A self-cleaning screen is formed via additive printing. The dimensions of the self-cleaning screen are modified. Supports are printed via additive printing. The supports are formed over a plurality of wires. Side seals may be additively printed along major sides of the plurality of wires. Wear of the screens is monitored.

The invention relates to a method and a system for separating dust-containing material mixtures which contain fibers, preferably glass fibers, and have heavy metal (SM) and/or precious metal (EM) from the process of recycling electric or electronic devices, wherein the method has at least one step (S1) of mechanically releasing particles from fiber-containing mixed material agglomerates in a dry manner and at least one step (S2) of mechanically releasing fiber-containing mixed material agglomerates in a dry manner.

An adjustable grizzly grid material separator is provided and includes a plurality of flexible tines, a cassette, wherein the plurality of flexible tines are each coupled on an end to the cassette to form a grizzly assembly. A plurality of grizzly assemblies may be coupled to a frame at an angle, wherein the grizzly assemblies are coupled to the frame in a grid configuration. The plurality of tines are spaced apart a predetermined distance to set the size of material that is to be separated from an amount of aggregate flowing over the tines.

An assembly for separating selected defective objects from a group of objects used in tobacco industry, the group comprising regular objects having a form of substantially spherical external surface of a determined diameter and the remaining objects being defective objects, the assembly comprising a sieve element (105) having through channels (106) or holes and a generally flat blocking element (107) located under the sieve element, the blocking element having an upper surface/107B) and through holes (108), the sieve element and the blocking element being displaceable in a direction parallel and/or perpendicular with respect to each other at least between a first configuration and a second configuration. In the first configuration the channels or holes of the sieve element, and the holes of the blocking element enable the regular objects and selected defective objects to enter the upper parts of the channels and they enable the regular objects to fall through the lower parts of the channels and through the holes of the blocking element, while they hold said selected defective objects. In the second configuration the channels or holes of the sieve element and the holes of the blocking element enable said defective objects held in the first configuration to fall through the assembly. A method of separating selected defective objects from a group of objects used in tobacco industry using the assembly according to the invention.
