AI Technical Summary
In existing pelletizing devices, there are gaps or excessive wear in the fit between the pelletizing blade and the pelletizing screen, and the center of the screen and the pelletizing blade cannot be precisely matched, which affects the service life of the equipment and the pelletizing quality.
The sizing blades, made of elastic material and with carbide cutting edges, fit snugly against the sizing screen. The screen position can be adjusted by adjusting screws and a suspension structure to ensure precise fit. The sizing blade hub and the rotating shaft are connected by a pin for easy disassembly and assembly.
This achieves precise matching between the granulating knife and the granulating screen, improving granulation quality, extending equipment lifespan, and avoiding incompatibility issues caused by changes in specifications.
