To provide a biomass pulverizing device and a biomass/coal co-combustion system, allowing an efficient discharge of pulverized biomass powder to the outside.
This biomass pulverizing device includes: a pulverizing device body 13 having a raw material supply pipe 12 supplying biomass material 11 from above in the vertical direction; a pulverizing table 14 whereon the supplied biomass material 11 is placed; a drive part 15 rotationally driving the pulverizing table 14; pulverizing rollers operating in conjunction with the rotation of the pulverizing table 14 and pulverizing the biomass material 11 by pressing force; and a blast means forming an upward flow upward from below on the outer circumferential side of the pulverizing table 14, and jetting a carriage gas 18 airflow-carrying the pulverized biomass powder 17. The biomass pulverizing device further includes: an erected weir 14a formed on the periphery of the pulverizing table 14; and a first extended weir 31 which is formed with a plurality of slits, is extended from the pulverizing device body 13 side of lower parts of the pulverizing rollers, and forms a prescribed gap to the upper face side of the erected weir 14a.
