Description

Technical Field

[0001] The utility model relates to the technical field of disc pelletizers, and particularly relates to a disc cleaning device for a disc pelletizer. Background Art

[0002] The disc pelletizer is generally arranged obliquely, with a fixed width and height at the disc edge, and can complete the functions of nucleation, growth, and sorting of powdery materials: the disc surface mixes ore powder and binder under the rotation action to obtain mother balls. The mother balls that continuously adhere to ore powder move in a rolling and sliding manner in the pelletizing disc. As the particle size of the green balls continuously increases, when the frictional force provided by the disc surface and the powder is not sufficient to offset the component of gravity along the disc surface, the green balls start to slide and are discharged by parabolic trajectory on the pelletizing disc, completing the nucleation, growth, and sorting of the green balls. During the use of the disc pelletizer, materials will adhere to the inner wall of the disc. If the materials cannot be cleaned in time, the adhered materials will affect the production of mother balls by the subsequent pelletizer and the shape of the mother balls. For this reason, we propose a disc cleaning device for a disc pelletizer. Summary of the Utility Model
