Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a raw material screening device for a granulator. Background Art

[0002] A granulator is a forming machine that can manufacture materials into specific shapes. Its working principle usually involves the processes of mixing, forming, and granulating materials inside the machine. Granulators are widely used in many industries, including food, medicine, chemical engineering, and agriculture, etc. In the food industry, granulators can process various raw materials into granular substances, such as dried tofu, meat products, and biscuits, etc., improving production efficiency and reducing raw material waste. In the medicine industry, granulators can process drugs into granular substances of specified sizes, improving drug efficacy and reducing side effects. In the chemical engineering industry, granulators can process various powdery raw materials, such as fertilizers, pigments, and cosmetics, etc. In the agriculture industry, granulators can process seeds, feeds, fertilizers, etc. into granular substances, improving the yield and quality of crops. In order to improve the granulation effect, the raw materials need to be screened before granulation, so as to screen out the raw materials with larger sizes.

[0003] However, most of the existing screening devices screen through a sieve mesh. This method requires manual shaking of the sieve mesh during screening, increasing the labor intensity of workers. Prolonged use will lead to a decrease in screening efficiency. At the same time, the sieve mesh is not convenient to replace, so different raw materials cannot be screened, and its use has certain limitations. In view of this, the present utility model is specifically proposed. Content of the Utility Model
