摘要： 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.

摘要： A method for producing urea pellets having a narrow range of grain sizes and a sphericity >75% and a defined residual moisture ≦0.5% is provided. The method provides urea pellets having the properties required which meet the requirements of the automotive industry for use thereof in reducing emissions from diesel engines. The method includes spraying a urea-containing liquid having a temperature between ambient temperature and above the melting point of the urea into the high particle density region of the spray zone of a near circular gas, material flow of a spouted bed apparatus and onto the particle surface of the material, which is dried and granulated in the gas flow at a temperature of not more than 130° C. at a controlled heat and mass transfer rate while being separated.

摘要： A method for producing granules made from malt extract is provided. The method provides for producing granules continuously or in batches under the prevention as much as possible of non-uniform temperature distributions in the production process. Simultaneously, the controllability of the granulation in the production is improved. This is realized by linking thermal conditions in the spraying zone and the temperature conditions in other region of the apparatus. This is achieved such that the supply of the heated process gas for drying is realized exclusively in the spraying region. The reliable supply of particles into the spraying region is performed through the special geometric configuration of the apparatus under the use of gravity.
