PLANT FOR GRANULATION OF EXTRUDED MATERIAL Russian patent published in 2023 - IPC B29B9/06 

FIELD: granulating plasticized extruded materials.

SUBSTANCE: invention relates to a plant for granulating plasticized extruded material. The granulation plant contains a body (1), a granulation unit, a puller, a perforated plate. The housing includes pipelines (2) and (3) having a rectangular cross section for supplying gas. The pipeline (2) is in the direction of the body flow. The granulation unit is at least partially located in the housing. The plate (4) of the feeding or plasticizing block (27) is connected to and/or enters the housing. The puller (6) crushes the material coming out through the recesses (5) of the plate. In the plane or plane (E-E) of the section located parallel to the plane of the plate and/or the front wall (17) of the casing, both side surfaces (7) of the walls of the pipeline (3) located perpendicular to this plane form an angle α2 with each other. Both side surfaces (8) of the pipeline walls (2) located perpendicular to this plane form an angle α1. Both corners α1, α2 open towards the housing (1). Angle α1 is greater than angle α2. Between the housing and pipeline (3) for gas removal is located or built-in adapter housing (100).

EFFECT: rapid curing of the separated particles is achieved and both the mutual collision of the particles with each other and the collision of the particles with the inner walls of the housing are prevented.
