The invention relates to a three-roller rolling head unit of a planetary mill. The three-roller rolling head unit comprises three rolling heads which are uniformly arranged in a circular rotary disc in a trisected manner; each rolling head is in the shape of circular cone; each rolling head sequentially comprises a tail gripping region, a middle intensive deformation region, a head leveling region and an outlet sizing region from tail to the top end; a plurality of concave-convex lines are arranged between each tail gripping region and each middle intensive deformation region in the radial direction; and oblique lines formed by axial projections of the concave-convex lines are sine curves. The three-roller rolling head unit is simple in structure, is compact in design and is convenient to use; when rollers with the concave-convex lines rotate at a high speed, casting blank can be gripped into the middle intensive deformation regions very well, so that blank advance resistance is reduced, and rolling force, in
