PROBLEM TO BE SOLVED: To provide an innovative constitution of a jet mill for easily carrying out cleaning and washing of every lot of the jet mill. SOLUTION: This jet mill is so constituted as to form a milling chamber 1 between an upper stage 31 and a lower stage 32 of a supporting stand 3 in a detachable manner and so that the milling chamber is firmly pressed aginst the lower face of a sieving chamber 2 fixed on the supporting strand 3 by a lift device 4. In addition to such a constitution, the milling chamber 1 and other members such as pipelines are enabled to be joined by a freely detachable free joint capable of attaching and detaching these members by one touch, so that disassembly and assembly at the time of cleaning and washing can easily be carried out. Further, O-rings are used in the joining parts of the milling chamber 1 and other members to keep air-tightness.
