Sludge Thickening
So-called "swirl separators," an example of which is illustrated in Figure 7-98, are devices that use a relatively low centrifugal force to separate grit.The source of energy for these devices is normally a pump. The pump causes wastewater to flow through the swirl separator at a velocity sufficient to cause grit, or other high specific gravity material, to …

Improving control and yield in gravity thickeners
The technique is used in the same way in both industrial and municipal settings. A gravity belt thickener employs 'gravity drainage', i.e. dilute sludge (typically 0.5% to 1.0%), which is introduced at the feed-end of a horizontal filter belt. As the slurry makes its way down the moving belt, any free water drains through the porous belt.
Five Kinds Technology Of Manganese Ore Beneficiation
Gravity separation methods include heavy media, jig, and shaking table beneficiation. Before gravity separation, the manganese ore is first crushed (6-0mm or 10-0mm) and then classified. The coarse-grained manganese ore particles enter the jig for sorting; the fine-grained ore particles are sent to the shaker for sorting.
