MIXING DEVICE

Japanese Patent JP3136117

B2

PROBLEM TO BE SOLVED: To provide a mixing device in which structure is simple and both pulverization efficiency and mixing performance of the material to be mixed are enhanced.
SOLUTION: The mixing device is equipped with a rotary shaft 3 provided so as to be rotated and driven around the shaft in a vessel 2 of material to be mixed, with agitation members 4 and fluidization direction-changing members 7 provided so as to be accompanied and rotated and with pulverization members 6 which are provided so as to be rotated and driven in the inner circumferential part 2a' of the vessel 2 opposite to the outer circumferential part of the rotary shaft 3. The agitation members 4 are arranged with the intervals in the direction of a rotary diameter for the outer circumferential part of the rotary shaft 3 and have agitation faces fluidizing the material to be mixed toward the outer circumferential part of the rotary shaft 3. The fluidization direction-changing members 7 are arranged with the intervals in the direction of the rotary diameter for the inner circumferential part 2a' of the vessel 2 between the agitation faces and the outer circumferential part of the rotary shaft 3. Also, the members 7 have change faces 7d' which change fluidization direction of the material to be mixed from the direction directed to the outer circumferential part of the rotary shaft 3 to the direction directed to the inner circumferential part 2a' of the vessel 2.
