Abstract (en)
[origin: EP0305748A2] Powder preparation installation, in particular for enamel powder. <??>In a preparation container (2) fluidised powder is moistened to a particular moisture content by feeding in a compressed air stream which is controlled with respect to moisture content and temperature. Powder which has reached the correct moisture content in the preparation container (2) is transferred into a powder container (114). A spray device 10 for the electrostatic spray coating of an object with powder receives the powder from the powder container (114). As a result, it is ensured that only such powder is sprayed by the spray device which has the optimum moisture content for an electrostatic spray coating. The preparation container (2) contains a plurality of heating zones which can be heated separately from one another and are arranged on top of one another. As a result, only relatively small amounts of powder have to be adjusted to relatively large moisture content changes and temperature changes in the preparation container 2 when fresh powder and powder recovered from coating booths flows into the preparation container (2). <IMAGE>
