PROBLEM TO BE SOLVED: To provide a pneumatic crusher that allows an operator to easily and quickly adjust its classifying performance while keeping its crushing capacity unchanged, and is free from a risk of being contaminated with foreign matter during the adjustment work.SOLUTION: An inlet-side rotary blade 5 and a discharge-side rotary blade 6 are cantilever-supported with a specified gap apart in a casing 10 including a cylindrical body 11 and a taper-shaped front lid 12, and a crushing area 15 of a specified volume is constructed by the rotary blades 5, 6 and the inner circumferential wall face of the casing 10. The position of the taper-shaped front lid 12 is made adjustable relative to the cylindrical body 11 of the casing 10, and the classifying performance of a classifying area 21 formed between the taper-shaped front lid 12 and the tapered part 9 of the discharge-side rotary blade 6 is made variable. |
