A device for imparting vibrational energy to polymeric pellets in a feed path of an extruder is disclosed. The device includes a feed path vibrator having an elongate imparting portion for being disposed within the feed path of the extruder, and a transfer portion extending from the imparting portion. The transfer portion is configured for coupling to a source of vibration energy, and the elongate imparting portion includes at least one twisted portion along its length.

A feeding system for feeding a powder material to a moving powder mass includes a moving device structured to move the powder mass along a movement direction and a feeding reservoir that is structured to provide the powder material to be fed to the moving mass. The feeding reservoir includes a plurality of feeding openings dimensioned for feeding the powder material to the moving powder mass. At least some of the plurality of feeding openings being arranged along the movement direction of the moving powder mass.

A method for producing absorbent, fiber-based, in particular cellulose fiber-based, granular material as pellet-like units, wherein fiber-based starting-material parts are pressed through a granulating channel having a feed region, a compaction region and a loosening region and are crushed between two rollers. A device for carrying out the method is also disclosed.

A system and method for processing powdered materials. The system has a first roller, a second roller, and a compression zone for compressing the powdered material between the rollers. At least one oscillating guide plate is provided that has a curved edge that face the first roller. A curved channel is formed between the curved edge and the first roller. The curved channel tapers from a wide entrance opening to a narrower exit opening. The exit opening leads into the compression zone between the rollers. The curved channel receives the powdered material and compresses the powdered material as the powdered material advances. However, due to the curvature of the curved channel, the powdered material is sheared as it is transitioned and redistributed to the narrower cross section while gaining uniformity of flow and density. The result is that a compressed powdered material with generally uniform density.

An evaluation device (20) evaluates the operating conditions of a briquetting machine (10). The evaluation device (20) includes an evaluation information acquisition unit (220) and an evaluation data generation unit (230). The evaluation information acquisition unit (220) acquires a plurality of pieces of evaluation information indicating the evaluation results of a plurality of briquettes manufactured under the same manufacturing conditions by the briquetting machine (10). The evaluation data generation unit (230) generates evaluation data that is data obtained by comparing a plurality of pieces of evaluation information with each other.

A machine for dry decoration of ceramic slabs or tiles, comprising: a support element (10), provided with a plurality of cavities (11) with a pre-established shape; a dispensing device (20), configured to deposit a pre-fixed amount of powder material inside one or more pre-established cavities (11); an unloading device (30), configured to move the cavities (11) from a loading position, in which they can receive the powder material from the dispensing device (20), to an unloading position, in which they can unload the powder material.
