PROBLEM TO BE SOLVED: To provide an agitation apparatus which can fully mix agitate a raw material to be agitated while moving it to an exhaust opening in a rotary cylindrical body, also fully dry the raw material to be agitated, and separate the material to be agitated into pieces of aggregates and powder and which can prevent the raw material to be agitated, sticking to the inner surface of the rotary cylindrical body, from growing over the height of a lifting plate, and make powder sufficiently float to be effectively recovered. SOLUTION: The agitation apparatus has the rotary cylindrical body 1, the inner surface of which keeps a plurality of lifting plates 4 projectedly arranged, wherein the lower end of a screw blade 5, installed to a rotary shaft 50 which is inserted into the inner part of the rotary cylindrical body in the axial direction to be axially supported, is axially supported as to come close to the lifting plates downwards the inner part of the rotary cylindrical body, and a powder sucking apparatus 7 for recovering floating powder by aspirating the inner air of the rotary cylindrical body, wherein the powder sucking apparatus is formed so that this apparatus makes the raw material to be agitated move towards the exhaust opening 11 while making the raw material to be agitated mix agitate by rotation of the screw blade.
