Description

Technical Field

[0001] The present application belongs to the technical field of dry granulation, and in particular to a dry granulation device with a self-feedback roller angle that can be dynamically adjusted. Background Art

[0002] Dry granulation is a granulation technology that uses mechanical force to compact powder materials into blocks or flakes with a certain hardness, and then makes granules through a screen. This method does not require the use of liquid adhesives and is suitable for materials that are sensitive to moisture or need to avoid moisture. Compared with the wet granulation process, the dry granulation process has the advantages of simplified process flow, reduced energy consumption, and lower production costs. In addition, dry granulation can reduce dust pollution, improve the fluidity and mixing uniformity of materials, and help improve the stability, disintegration and solubility of the product.

[0006] 2: The dry process exploration process is time-consuming, labor-intensive, and material-consuming, and in the end, it may not be possible to complete granulation using the dry process;

[0007] 3. Long-term multi-batch production, poor stability, and excessive human intervention lead to uneven and unstable quality of the preparation.
