粉末状の材料を製造しかつ/または状態調節するための方法および装置

Japanese Patent JP5086365

B2

A method and a device for producing and/or conditioning powdered material. The aim of the invention is to provide a method and an associated device which are used for producing and/or conditioning powdered material in a spouted bed comprising inert particles and in which a dry, fine powder having a very small particle diameter is produced at a low cost and at adequately large quantities in a continuous operation. This aim is achieved by a method in which the material is treated in several stages in a spouted bed comprising inert particles. In the method, the powdered material that is preprocessed in a first spouted bed and is separated from the larger material particles in an integrated dust collector is fed to a superimposed second spouted bed as a material-gas flow along with the gas flow discharged from the first spouted bed in order to be further reduced in size and be conditioned. After separating the fine particles from the larger material particles in a dust collector that is integrated into the second stage, the fine particles are discharged from the two-stage spouted bed treatment along with the gas flow as a powdered material having very small particle diameters. The separated larger material particles are once again fed to the second spouted bed of the second jet chamber. The device includes a spouted bed apparatus in which a jet chamber encompassing an integrated dust collector as well as a second superimposed jet chamber encompassing another integrated dust collector are disposed.
