Description

Technical Field

[0001] The utility model relates to the technical field of cement feeding, and more specifically, to a cement feeding device for a cement production line. Background Art

[0002] A cement feeding device for a cement production line is a key device used to transport raw materials (such as limestone, clay, iron powder, etc.) to the cement production line during the cement production process.

[0003] In the existing technology, firstly, the materials in some devices may not be mixed evenly, affecting the quality of cement. Manual or simple mixing methods cannot achieve high production efficiency, affecting the production capacity of the production line. A large amount of manpower is required for stirring, increasing labor intensity and cost. Secondly, the materials in some devices may not flow smoothly in the mixing tank, resulting in uneven mixing or blockage, which may cause dead corners in the mixing process and affect the mixing effect. Finally, some devices may cause inaccurate material addition, affecting product quality and formula ratio. The instability of material addition may cause fluctuations in the production process, affecting production efficiency and product quality. There is no automated material addition, and manual operation is required, which increases the complexity of the operation and the possibility of errors. Utility Model Content
