HYDRAULIC CYCLONES FOR THORIUM OXIDE PARTICLE SIZE CLASSIFICATION

PDF Version Also Available for Download.

Description

Results are reported concerning studies of hydraulic cyclones (hydroclones) for application to particle size classification of ThO/sub 2/. Tests were run with a 0.50-in. diam. hydroclone. It was shown that a single pass through this hydroclone would reduce the material greater than 10 mu from 12 wt.% to less than 1% while the mean diameter was reduced from 1.7 to 0.9 mu . When the overflow (fine) fraction was again pumped through the hydroclone, the overflow solids from the second pass were 98 wt.% less than 2 mu in diameter. The mean diameter was reduced from 0.9 mu to about ... continued below

Description

Results are reported concerning studies of hydraulic cyclones (hydroclones) for application to particle size classification of ThO/sub 2/. Tests were run with a 0.50-in. diam. hydroclone. It was shown that a single pass through this hydroclone would reduce the material greater than 10 mu from 12 wt.% to less than 1% while the mean diameter was reduced from 1.7 to 0.9 mu . When the overflow (fine) fraction was again pumped through the hydroclone, the overflow solids from the second pass were 98 wt.% less than 2 mu in diameter. The mean diameter was reduced from 0.9 mu to about 0.7 mu by the second pass. A yield of 5 to 7 wt.% of solids (to the overflow streamn) and a ratio of overflow to feed volume of 0.25-0.30 were observed during the hydroclone tests. Although this low yield is undesirable, recommendations are made that would increase the yield sufficiently to make desirable the incorporation of hydroclones in the ThO/sub 2/ production flow sheet.
