[0002] Powder material balling, granulating equipment is widely used in chemical industry, building material, metallurgy and environmental protection and many other industries, and it is an important equipment in industrial production, among which disc granulator is most widely used. The working principle of disc granulator is that a disc with a periphery is installed on the main shaft in the middle of the equipment at a certain inclination angle between the disc and the horizontal plane. The disc is driven to rotate by a pair of triangular belts, a cylindrical gear reducer and a pair of bevel gears. The working principle of disc pelletizing is that the material rolls in the inclined rotating disc. The inclined disc causes the powder to fall, and the collision and friction between the particles increase due to the fall. The material moves along a certain trajectory under the action of multiple forces to form a rolling vortex. After adding a certain amount of water, the particles in the disc become larger, the crystal nucleus gradually increases, and after a certain period of time, round particles are formed until the required particle size is reached.

[0028] In addition, the terms "first" and "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "multiple" is two or more than two, unless otherwise specifically limited. In addition, the terms "mounting", "connecting", "connecting" should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0029] As Figures 1 to 5 shown, the 3D disc balling machine for vanadium-titanium pellets of the utility model embodiment, including base 5, scraper fixed frame 6 and disc 7, the disc 7 rotatablely installed on base 5, scraper fixed frame 6 is installed on the top of disc 7, at least two fixed scrapers are installed on scraper fixed frame 6, each fixed scraper is arranged in the interior of disc 7 respectively, each fixed scraper is arranged between the center of disc 7 and the outer side wall of disc 7 in sequence respectively, and the blade extension line of each fixed scraper forms a certain angle with the bottom surface of disc 7, so that the material bottom surface formed by each fixed scraper after the rotation of disc 7 can jointly form a complete conical material bottom surface.

[0030] Due to the adoption of the above-mentioned structure of the plurality of fixed scrapers, the 3D disc pelletizer for vanadium-titanium pellets of the embodiment has the advantages of simple structure, no need to set an additional motor, and reduced energy consumption, compared with the conventional rotary scraper disc pelletizer. Since the entire disc material bottom surface can form a 3D curved surface with a taper after the disc rotates, the ball movement trajectory and running speed are changed, the material moisture adaptability is stronger, and when the material runs to the top of the disc, the material is more likely to roll and form green balls due to the larger inclination angle between the disc bottom material and the ground. When the material runs to the center point to the disc bottom, the inclination angle between the disc bottom material and the ground is smaller, the material is in deceleration, which is beneficial to improve the green ball density and material classification, and ensures the green ball yield and product quality.

[0031] Specifically, an included angle a is formed between the blade extension line of the fixed scraper and the bottom surface of the disc 7, where 10° > a > 0°. The size of the included angle a can be set according to actual use requirements to further reduce the disc surface running resistance.
