Method for contactless characterization of granule package e.g. raw material package, involves exciting moving non-fixed particles of package by application of external magnetic force without enabling movement of fixed particles

摘要

The method involves exciting moving non-fixed particles of granule package by application of an external magnetic force without enabling movement of the fixed particles. The movement of the non-fixed particles is determined by contactless measurement using laser measuring method, X-ray radiography method, and magnetic resonance or radar measuring method.
