Process for fluidising particles and apparatus for carrying out the process

摘要

A particle vortex process, comprises passing the particle, through a vortex gas stream to a vortex layer. Pressure measurements are taken in or along the vortex layer, and a measure for the distribution of these values is determined. The speed of the vortex gas stream is then controlled based on the measurement. The measure is pref. the standard downstream of the measured values. The process is used in the application of powder lacquers. The vortex is easy to control and the process is simple to carry out.
