The chain wheel of the plate chain bucket elevator consists of wear-resistant driving chain wheels and tension chain wheels, with advantages including high wear resistance, easy maintenance, long service life, high lifting efficiency, fully enclosed design, strong adaptability, and high lifting height.

The process of head wheel machining: Chain wheel blank (purchased from outside) → Turn end faces, outer and inner circles (vertical lathe) → Mill teeth (gate milling machine) → Heat treatment → Insert key slots (insertion lathe) → Drill fastening screw holes (drilling machine).
