Abstract:
To improve strength of a support part.SOLUTION: A mill includes: a housing forming an outer shell; a crushing table which is housed in the housing and in which a solid fuel is supplied to an upper surface; a crushing roller which is housed in the housing and crushes the solid fuel supplied to the upper surface of the crushing table; a journal head 45 which supports the crushing roller in a manner that the crushing roller can swing around a center axis C, extending along a horizontal direction, relative to the housing; and a pressing device which presses the journal head 45 so as to swing and press the crushing roller against the crushing table. The journal head 45 has: a pressure receiving part 53 which is pressed by the pressing device; and a support arm 47 provided between the pressure receiving part 53 and the crushing roller. In the support part 47, an arm part 60, located at a front part in a pressing direction of the pressing device, curves so as to protrude forward in the pressing direction.SELECTED DRAWING: Figure 2
