Method and device for characterizing physical properties of granular materials

摘要

The invention relates to a method and a device for characterising physical properties of granular materials. In order to obtain sufficient information about the shape and content of the individual particles of the granular material, the device for carrying out the method comprises an optical measurement section that, in order to carry out a laser triangulation, comprises at least one laser (16) and two cameras (12), an x-ray or gamma beam measuring device (18, 20) comprising an x-ray or gamma-ray source (18) and an x-ray or gamma-ray detector (20) arranged opposite said source, and a conveyor device (14) that moves the granular material along the measurement sections of the laser triangulation (12, 16) and the x-ray or gamma-ray measuring device (18, 20) in a mechanically supported manner.
