Description

Technical Field

[0001] This utility model relates to the field of granulation equipment technology, specifically a mixed granulation equipment. Background Technology

[0002] Mixing granulation equipment, commonly known as a mixing granulator, is a high-efficiency, multi-functional device that combines mixing and granulation functions. It can provide comprehensive solutions for the processing of various powders, liquids, and viscous materials, and its main application areas include chemical, pharmaceutical, food, and agricultural industries.

[0003] In existing mixing granulation equipment, the angle of the stirring blades is usually fixed and cannot be flexibly adjusted according to the material characteristics and production needs. This results in the stirring force on the material being unidirectional during the mixing process, affecting the quality and consistency of the final product. At the same time, the fixed angle of the stirring blades also limits the control of the force state of the material during the granulation process, resulting in a relatively uniform particle size and distribution of the final product.

[0004] In view of the above, this application is hereby submitted. Utility Model Content
