DRUM-SCREW UNIT FOR GRANULATION OF MAN-MADE MATERIALS AND THEIR PROCESSING Russian patent published in 2021 - IPC F26B11/04 

FIELD: material processing.

SUBSTANCE: drum-screw unit for the granulation of man-made materials and their processing is intended for the processing of highly dispersed carbon-containing and other mineral and organic materials. The unit constitutes concentrically located drums rigidly fastened together. The novelty in the design of the unit is the placement between the loading device (1) and the central drum (7) of a spiral microgranulation block (3), which promotes the formation of micro-embryos. The central drum (7) has a partially hollow central shaft (8) with located on it, in its loading part, installed in pairs, multidirectional two-way, helicoidal blades (9). In the middle part of the central drum, in the granulation zone, on the shaft (8), one-way screw blades (10) directed towards the unloading side are sequentially installed. Further, on the central shaft 8, in the granulate classification zone, one-way multidirectional helical blades (11) are placed. The outer drum (17) is made with a classifying mesh surface in the unloading part. The central drum (7) in the unloading part also has a mesh surface. The coolant circulation pipeline is equipped with a recirculation unit (24).

EFFECT: invention makes it possible to provide microgranulation and processing of granulated organic solid waste.
