yellow cake dust conveying velocity
yellow cake dust conveying velocity
(OP)
hi Folks
repost from nuclear engineering forum
do anyone has any reference regarding the settling velocity of yellow cake (uranium oxide) dust.
Need it to ensure min velocity is adhered to prevent settling in duct system
thanks

RE: yellow cake dust conveying velocity
Description
MATERIAL:
10-15% by weight Uranium Trioxide (yellow cake). 8% Ammonium Sulfate in water solution. Specific gravity of slurry is 1.8.
Slurry grind suspension from 30% plus 20 mesh to 100% minus 20 mesh.
Grinds to 100% minus 20 mesh. Need extra horsepower because of high specific gravity.
AB MIXER:
Model 6 x 3, toothed impeller/liner, 20 HP, 1800 RPM, 1/8" grid. Dicon recirculates slurry at 25 gpm to 250 gallon tank.
BENEFITs Grinds to 100% minus 20 mesh. Need extra horsepower because of high specific gravity.

Pneumatic conveying can be a mixture of science and art. I've seen 2,000-9,000 fpm as a minimum velocity recommended to keep materials in suspensions. This value is very dependent on the density of the particles as well as the particle sizes being conveyed. You should account for the entire distribution, not just the [D4,3] average.
Perhaps you should quantify your material (density, particle size distribution) and see if there is any published literature on similar materials if you cannon find your exact one.
