The utility model discloses a wear-resistant spiral feeding shaft for preparing ferronickel slag powder through a vertical mill process, which comprises a shaft body and spiral blades, the spiral blades are arranged on the periphery of the shaft body, a plurality of wear-resistant scrapers are arranged on the spiral blades at preset intervals along the edge of the periphery, each wear-resistant scraper is fixed with the corresponding spiral blade in a threaded manner, and the spiral blade is fixed with the shaft body. And the spiral blade is provided with a wear-resistant sleeve layer coatingthe shaft body. The abrasion-resistant spiral feeding shaft can effectively reduce abrasion of the spiral blades and avoid abrasion of the shaft body, reduces maintenance and replacement cost, and meanwhile avoids reduction of spiral feeding capacity caused by bonding of raw materials on the shaft. 本实用新型公开了一种用于立磨工艺制备镍铁渣粉的耐磨螺旋送料轴，包括轴体与螺旋叶片，所述轴体外周设有所述螺旋叶片，所述螺旋叶片沿外周边缘间距预设距离地设有若干耐磨刮片，每一耐磨刮片与螺旋叶片螺接固定，所述螺旋叶片上设有包覆轴体的耐磨套层。本实用新型所述
