bulk density test of gypsum powder

Increasing Powder Bulk Density - bulk-online

I am looking for ways to increase the bulk density of a powder. The particle size averages 5 - 15 microns and I am trying to load a cylinder that is about 2 cu.ft (~11" diameter). The settling time for this material is quite high and I need a way to compress/compact/deaerate the powder in a reasonably short time frame. Any suggestions would be greatly appreciated.
