DEVICE AND METHOD FOR DETERMINING THE TRANSPORT BEHAVIOR DURING THE PNEUMATIC CONVEYANCE OF GRANULES

摘要

The invention relates to a method for determining the transport behavior during the pneumatic conveyance of granules, in that (A) the granule sample is placed in a conveying trough, (B) the granule sample is introduced into a controlled air flow downstream of the conveying trough using an injector, (C) the granule sample flows through a conveying section, and (D) the granule sample is measured in a laser diffraction spectrometer, wherein in step (B) the granule sample is introduced via a Venturi injector. The device for performing the method comprises a conveying trough for placing granules onto the conveying section, a conveying trough for placing unstressed granules into the laser diffraction spectrometer, an air flow control valve, a Venturi injector, a conveying section, and a laser diffraction spectrometer.
