Mill roller and pulverizer

A mill roller comprising:

• a roller main body having an outer peripheral surface, the roller main body rotating about an axis line, and configured to pulverize an object to be crushed against a mill surface of a mill table wherein the outer peripheral surface comprises:
• a first outer peripheral surface curved so as to form a convex shape outward in a radial direction orthogonal to the axis line of the roller main body, and having an arcuate shape formed with the same radius of curvature on both sides of a maximum outer diameter point formed about an axial direction of the outer peripheral surface in a cross section including the axis line;
• and
• a second outer peripheral surface formed on both ends in the axial direction of the first outer peripheral surface, connected to an end surface facing an axial direction of the roller main body, and receded further inward in the radial direction of an imaginary circle than an imaginary circle running along the first outer peripheral surface.
