PROBLEM TO BE SOLVED: To provide a biomass mill whose crushing capacity can be improved by promoting discharge of wooden biomass to the outside of a mill.SOLUTION: A biomass mill includes: a housing 3 forming a classifying chamber 17; a crushing table 5 housed at the lower part of the housing and driven by a table driving device 7; a plurality of pressurizing roller units 11 having pressurizing rollers 12 pressed to the crushing table; a blow-out port 19 blowing out primary air from the periphery of the crushing table; a chute 21 supplying wooden biomass to the center of the crushing table; and a flow contraction cylinder 22 covering the periphery of the chute. A flow contraction flow path 28 reducing the flow path cross section of the primary air discharged from the blow-out port is formed between the flow contraction cylinder and the housing. |
