Abstract:This paper introduces the structure and working principle of several feeding devices used in aluminum electrolysis multi-functional crane, and compares and analyzes the problems existing in their practical application. This paper introduces the structure design and working principle of the new feeding device. Many problems existing in the original structure are modified on the new structure. With high working efficiency, the new structure can meet the needs of the modern development of new aluminum electrolysis equipment, and can be widely promoted and applied.
