AI Technical Summary

Technical Problem

Traditional granulator feeding devices have an integral shell structure with a closed internal chamber. When cleaning material residue, tools are difficult to penetrate and cannot completely remove accumulated material in dead corners. Furthermore, replacement of worn or malfunctioning parts is time-consuming, affecting the purity of the feed and the operating efficiency of the equipment.

Method used

The design features a detachable lower and upper shell cover, allowing components such as the rotating rod and spiral blades to be disassembled independently. Combined with structures such as arc grooves, discs, rings, and sealing gaskets, the shell can be detached and sealed, facilitating cleaning and quick component replacement.

Benefits of technology

It achieves complete removal of residual materials, ensures the purity of the feed and the hygiene of the equipment, shortens maintenance time, and improves the stability of equipment operation and production line efficiency.
