Description

Technical Field

[0001] The utility model belongs to the technical field of adhesive mixing, in particular to adhesive production mixing equipment for iron ore powder disc granulation. Background Art

[0002] In the production process of iron ore powder disc granulation, the use of binders is a common method to improve the strength and quality of the particles. The uniform mixing of the binder raw materials is crucial to ensure the quality of the finished product. Traditional mixing equipment usually uses a single stirring device for mixing. However, due to the characteristics of the raw materials and the limitations of the stirring equipment itself, it is often difficult to achieve the ideal uniform mixing effect. Problems include insufficient mixing, uneven mixing in some areas, etc. These problems directly affect the quality and efficiency of subsequent granulation production. Inadequately mixed binder powder raw materials will lead to unstable particle quality and even particle breakage or poor bonding during iron ore powder granulation. Therefore, we propose a mixing equipment for the production of binders for iron ore powder disc granulation. Utility Model Content
