Provided is a roller mill that is provided with: a rotary table (12); a raw coal adding tube that supplies solid fuel to the rotary table (12); and a roller (13) that rotates about a rotating shaft (21) by being pressed against a grinding surface (12c) of the rotary table (12) and grinds solid fuel along with rotation of the rotary table (12). In such a roller mill, a position (P1) where an outer peripheral surface (13a) of the roller (13) and the grinding surface (12c) of the rotary table (12) come into contact with each other and a circumferential velocity of the outer peripheral surface (13a) equals a circumferential velocity of the grinding surface (12c) is located further to an inner circumferential side of the rotary table (12) than a position (P2) where the outer peripheral surface (13a) and the grinding surface (12c) come into contact with each other at a center position in a width direction of the roller (13).
