DEVICE FOR CLEANING BULK MATERIALS WITH A BUILT-IN AIR SEPARATOR, AS WELL AS A DEVICE FOR CLEANING BULK MATERIALS WITH A HOLLOW CARRIER FRAME Russian patent published in 2022 - IPC B07B4/08 B07B1/28 B07B1/40 

FIELD: bulk materials processing.

SUBSTANCE: invention is intended for the processing of bulk materials. The device (1) for processing bulk materials contains a supporting frame (2) and a sieve housing (3) mounted on the supporting frame using spring elements with the possibility of bringing it into rocking and/or vibrating by means of a drive. At least one sieve (6) is located in the sieve housing (3) to separate the bulk material into the first fraction (F1) and the second fraction (F2). The sieve housing has one loading hole (7) and at least two outlet holes (8, 9), respectively, for the first fraction (F1) or the second fraction (F2). The device (1) for processing bulk materials contains an air separator (10) fixed only on the sieve housing (3), therefore, the air separator (10) is also driven by the drive (5) in rocking and/or vibration.

EFFECT: compactness, energy saving during operation.
