Description

Technical Field

[0001] The utility model relates to the field of granulation equipment, and more particularly to a side leakage-proof dry granulation pressing wheel structure. Background Art

[0002] A granulator is a device specifically used to convert powdered materials into granules. It is widely used in the pharmaceutical, chemical, food and other industries. Compared with traditional wet granulation, dry granulation has significant advantages and has gradually become the preferred technology in many production processes. The workflow of the dry granulation wheel structure includes the preparation stage, feeding stage, pressing stage, discharging stage and cleaning and maintenance stage.

[0003] However, in the traditional powder pressing process, the dry granulation wheel structure still has technical defects. Due to the light powder and small particle size, the material will fall from both sides of the wheel, resulting in uneven quality of the pressed cake, which may lead to uneven particle size and density, and even differences in performance. It cannot meet the market's strict requirements for high-quality granular products. Therefore, it is necessary to design a dry granulation wheel structure that prevents side leakage to solve the above problems. Utility Model Content
