Method and the device which inspect the strength quality of the granule

摘要

(57) Abstract This invention granting the damage which has reproducibility in the above-mentioned granule, by vibrating the small-sized container which shuts in the granule with the amplitude which is controlled sufficiently is something which offers method and the device which measure the shocking strength of the granule. The degree of damage which is added to the granule it is measured as function of time and amplitude. The expedient which possesses the high reproducibility which inspects the quality of granule grinding and crushing with the measurable quantity which is obtained is produced.
