A method for the production of fine ceramic pressing granulate by means of eddy layer granulation drying

摘要

the invention concerns a method for the production of feinkeramischem preu00dfgranulat through the wirbelschichtgranulationstrocknung, with the resulting granules of a downstream preu00dfformgebung corresponds.$a erfindungsgemu00e4u00df is achieved by the china schlicker to liquefaction related condenser and as binder and polyvinyl alcohol (pva) preu00dfhilfsmittel polyvinyl acetate (pvac), and polysaccharide / acrylic acid (ps / ac) in the amount of 0.4 to 1.5 mass%, related gene on the trockenstoffanteil of schlickers,compared with pva, pvac: hp / ac (40 + 20): (50 + 25): (10 + 10% so that the schlicker are added to a moisture content of 38 + 3% and a density of (1600 + 50) g / l, and that the zulufttemperatur of heat to wirbelschichtgranulationstrocknung of feinkeramischem preu00dfgranulat 180 to 250u00b0c and of 40 to 100%.
