(54) DRUM DRYING GRANULATOR

(57) Invention m. used in drying high moisture materials

with simultaneous granulation. The purpose of the invention is the intensification of day and granulation processes. The rotating drum 1 has a nozzle 5 at one of the ends and a reverse screw 2, made in the form of a closed multi-way with a dense arrangement of approaches, a groove. The approaches form with their surfaces, facing the axis of the drum 1, a solid conical shell 3, directed by a smaller base towards the nozzle 5. The design of the dryer-granulator allows a more uniform spilling of the dry product in the form of a retur. 2 Il.

The invention relates to a technique for drying high-moisture materials with simultaneous granulation and can be used in various industries.

The purpose of the invention is the intensification of drying processes and granules.

FIG. 1 shows a dryer-granulator, a longitudinal section; in fig. 2 shows section A-A in FIG. one.

The granulator torus contains a rotating horizontally mounted drum 1, a reverse multiple worm screw 2, which forms a conical shell 3, a loading chamber 4, a fort hole 5, a device 6 for feeding an external retur, unloading chamber 7, lifting vanes 8.

Drum dryer-granulator works as follows.

In the rotating drum 1, the nozzle 5 sprays liquid onto the curtain formed by dumping the product from the lifting vanes 8. The wet granules are dried. In the heat carrier flow J moves from the drum head along the cone to the tail, i.e. towards unloading (at an angle of 1-4),

drum

at the same time, a part of the product is harvested from the drum through the unloading chamber 7, and the other part is transported along the reverse multi-seamy 2 from the tail section in the form of a retur. Due to the fact that the return auger has more entries (in FIG. 2 of the re approach), there is more dimensional dumping of the dry product of the retur. External Retur Usgroyst 6 is fed to the head

Formula of invention

The drum dryer granulator containing a rotating drum with a nozzle at one of the ends and a reverse auger was made in the form of a closed groove, which was different because, in order to intensify the drying and granulation processes, the groove was made multiple with dense

the placement of visits, forming. with their surfaces facing the axis of the drum, with the conical shell, directed by MeHbmHN with the base towards the nozzle.
