To provide a biomass crusher, which can efficiently discharge crushed biomass powder to outside, and a biomass-coal mixed combustion system.
The biomass crusher includes a crusher body 13, which has a material supply pipe 12 that supplies a biomass material 11 from above in the vertical direction, a crushing table 14, on which the biomass material 11 is placed, a driving part 15, which rotates the crushing table 14, a crushing roller 16, which interlocks with the rotation of the crushing table 14 and crushes the biomass material 11 by thrust, a blower means, which forms a rising current upward from under the peripheral side of the crushing table 14 and spouts carrying gas 18 that carries the crushed biomass powder 17 in an air current, and a classifier 19, which is provided inside the apex of the crusher body 13 and consists of an outer cylinder 19A and an inner cylinder 19B for classifying the biomass powder 17 accompanying the carrying gas 18. Either or both of the outer cylinder 19A and the inner cylinder 19B are movable in the vertical direction.
