PROBLEM TO BE SOLVED: To provide a biomass mill configured to prevent wood powder produced in milling from staying on a milling table, and furthermore to smoothly move the biomass after the milling in the peripheral direction, thereby improving the milling efficiency and increasing the milling capacity.SOLUTION: A biomass mill includes: a housing 3 for forming a classification room 16; a classifier 36 housed in an upper part of the housing; a milling table 5 housed in a lower part of the housing and driven by the table drive devices 4, 6; a pressing roller unit 9 having a pressing roller 11 pressed by the milling table; a primary air chamber 15 formed below the milling table, and introducing a primary air thereto; an air outlet 18 for blowing the primary air from the periphery of the milling table; and a chute 25 for supplying wood biomass in the center of the milling table. Air ejection pores 19 are bored in uniform distribution over the whole circumference of the milling table, and a second primary air 20b is spouted from the air ejection pores for floating fine particles after the milling. |
