Extraction Characteristics Of Bulk Materials From Silos Part 2: Experimental Results

摘要

As part of this work experimental investigations were carried out with a rectangular silo. The main focus was on the stress states during emptying by two silo extraction screws and the relationships between the wall normal stresses, the flow profiles and the torques required for the extraction screws. Among other things it was established that the wall normal stresses are lower in moving zones than in stationary zones.The findings and relationships that were discovered can be applied reliably to industrial plants. Part 2 of the article presents the experimental results.
