To provide a biomass crusher capable of efficiently and stably crushing a biomass raw material, and a biomass-coal co-firing system.
The biomass crusher includes a crusher body 13 having a raw material supply pipe 12 for supplying the biomass raw material 11 from above in the vertical axis direction, a crushing table 14 having a table liner 14b on which the supplied biomass raw material 11 is mounted, a driving part 15 for rotating and driving the crushing table 14, a crushing roller 16 operating in conjunction with the rotation of the crushing table 14 and crushing the biomass raw material 11 by a pressing force, and an air blowing means for forming an upward flow from below to above of the outer peripheral side of the crushing table 14, and for ejecting a carrier gas 18 which carries a biomass pulverized body 17 in an air stream. The table liner 14b of the crushing table 14 is formed by being divided into a plurality of fan-shaped segments, and the thicknesses of the respective segments in the height direction are different from each other.
