The utility model discloses an adjustable grinding medium feeding device for steel ball machining. The adjustable grinding medium feeding device comprises a frame body. The threaded rod is rotated to drive the second plate body, and then the roller body is driven to move. The positions of the grooves in the surface of the roller body are changed along with the change of the position of the roller body. The multiple sets of grooves in the surface of the roller body are designed in a gradient mode and tend to become large gradually from the starting end to the tail end.
