[0002] The automatic screw feeder for powdered raw materials is a type of automated equipment widely used in the chemical, pharmaceutical, food, plastics, and building materials industries. It is primarily used to automatically, evenly, and continuously transport powdered or granular raw materials from a storage silo to the next process or equipment in the production process. Its main components include a screw conveyor, motor, feed pipe, and control device.

This automatic powder feeding mixer delivers uniform feed without the formation of large agglomerates, significantly shortening polymer dissolution time, improving efficiency, reducing manual labor, and lowering costs. Feeding is performed within a closed feeding device, eliminating environmental pollution from dust and solvents. However, the automatic feeding device lacks screening and filtering of the powder. The particles inside the powder enter the feed sleeve under the action of the feeding motor, the spiral feeding slurry shaft and the spiral feeding slurry blade, which easily causes the particles to move between the spiral feeding slurry blade and the feed sleeve, causing wear of the spiral feeding slurry blade and the feed sleeve. Gaps are prone to appear in the worn areas, thereby affecting the feeding efficiency.
