Verfahren zur Herstellung von Granulaten in einer zirkulierenden Wirbelschicht, Vorrichtung zur Durchführung dieses Verfahrens und nach diesem Verfahren erhaltene Granulate |
摘要 |
The invention relates to a continuous method for producing at least approximately spherical, essentially solid particles, during which the particles are granulated in a circulating fluidized bed. This can be achieved, in particular, by: a) spraying a suspension or a solution of the solid substance that forms the particles in a chamber; b) permitting a dry gas to flow through the chamber at a speed that is sufficient for effecting a pneumatic transport of already partially dried or agglomerated particles; c) separating the particles transported by the flow of dry gas out from the flow of waste gas; d) at least partially feeding the particles separated out from the flow of waste gas to the chamber once more, and; e) continuously removing particles of a size located within the desired particle size range from the chamber so that the mass inside the chamber remains constant. The invention also relates to a device for carrying out said method, to particles that can be obtained by using this method, and to their use.
