[0002] Conditioning is a process of hydrothermal treatment of powdered materials before pelleting. Domestic and foreign studies have shown that conditioning is one of the important factors affecting the quality of pellet feed, and it plays a role of about 20% in the overall quality of pellet feed. Existing conditioners generally adopt a horizontal structure, and the material is transported and stirred in the conditioner by a screw conveyor. However, the way the screw conveyor pushes the material is through the principle of extrusion and pushing, so that a large amount of material is squeezed together, which is not conducive to the full mixing and conditioning of the material and water vapor.

The lower part of the side wall of the heating and tempering shell near one end of the axial thrust roller bearing is provided with a discharge port. When working, the material is put into the stirring and tempering shell 1 from the feed port 2, and the first driving motor 8 drives the hollow stirring shaft 3 to rotate. The first steam inlet 7 conveys water vapor into the hollow stirring shaft 3, and steam is sprayed to the material through the steam outlet 5 on the hollow stirring shaft 3. The stirring teeth 4 on the hollow stirring shaft 3 are used to feed the material. The material is stirred to achieve the first-level tempering of the material. The material is evenly tempered by water vapor through the stirring teeth 4. The feeding blades 6 feed the first-level tempered material into the heating and tempering shell 10 through the feeding port 9. The outer wall of the heating and tempering shell 10 is provided with a steam interlayer 11. The steam interlayer 11 heats and insulates the material inside to achieve the second-level tempering.

A bearing 15 is provided inside the retaining ring 14. The rotating disk 4 is symmetrically arranged on both sides of the bearing 15. The rotating disk 4 is fixedly connected to the inner ring of the bearing 15.

[0022] Preferably, a groove is provided on the inner wall of the retaining ring 14, and the outer ring of the bearing 15 is fixedly installed in the groove.

[0023] In the above arrangement, the transmission motor 8 rotates to drive the transmission rod 7 to rotate, and then drives the rotating disk 4 and the screw conveyor 2 to rotate. The screw conveyor 2 rotates to transmit the material entering from the feed port 5 along the tempering cylinder 1. At the same time, the bulk bar 10 moves in a circle along the axis of the screw conveyor 2. The driving gear 12 on the bulk bar 10 is meshed with the gear ring 11, so that the bulk bar 10 rotates with its own axis as the axis, thereby driving the bulk disk 13 to rotate.

[0030] In this embodiment, the material is added into the conditioning drum 1 through the feed hopper 16. Driven by the transmission motor 8, the screw conveyor 2 and the bulk rod 10 rotate, and the bulk disc 13 and the bulk convex plate 19 stir the material squeezed between the blades of the screw conveyor 2, so that the material is dispersed and fully mixed with the water vapor, while avoiding excessive local temperature, which is beneficial to improving the conditioning quality of the feed.
