DRUM VIBRATION GRANULATOR Russian patent published in 2019 - IPC B01J2/18 

FIELD: chemistry.

SUBSTANCE: invention relates to devices for pelletizing. Drum vibratory granulator is a vibroformer and vibro marumerizer in the form of cylindrical drums, located at angle of 3° to horizontal plane towards product unloading with belt mixers with blades and debalance type vibrators installed in them, which perform oscillatory movements in vertical plane. Vibratory tiller is equipped with loading hopper, nipple supply branch pipes and discharge of formed granules into vibrating skimmer with feed pipes and granules unloading, heat carrier supply and discharge nozzles located tangentially relative to the vale-hulker housing. To achieve high efficiency of finished product, minimum content of unformed granules and stable granulometric composition of obtained granules, vibroformer and vibro marumerizer perform oscillations of different frequency and amplitude, and belt mixers with blades rotate at different frequency in direction opposite to direction of particles movement. In order to prevent material sticking, the belt mixer slides over the inner surface of the housing, in order to reduce friction, the belt mixer is made of fluoroplastic.

EFFECT: invention can be used in food, chemical and related industries when processing loose materials into granular materials.
