we are studying packing procedures for large columns (50, 200, 400 mm diameter). We have noticed that if one applies vibration to the column after packing, it compacts a considerable additional amount. We can easily achieve an extra 7% compaction of the bed (measured in Height before/after vibration).
We observe this with compressible and incompressible media. It is impressive to see a packed column, which we had assumed to be tightly packed, to continue compacting under vibration.
Does anyone have any experience with this? What kind of vibration do you use, how long? Are your HETPs values better/worse?
Best regards,
