The LMC Marc Gravity Separator is the pinnacle of gravity separators. The Marc enables operators to make fine, definite separations with ease. The Marc eliminates the need for a middle cut and is the only gravity separator with an automatic discharge system. So whether you are processing seeds, edible beans, peanuts, or tree nuts, the Marc ...
Therefore, the inactive region of the feedwell is increased within the feedwell of larger diameter under the base condition’s flow rate. Fig. 7 RTD curves under different aspect ratios of feedwells As shown in Table 3, when aspect ratio is decreased from 1.5 to 0.5, the dead zone fraction also decreases from 37.83% to 23.90% and the …
Extraction of fines from any dry granular material at cut points between 35 and 200 mesh, without attrition loss. The Fluidizer Bed Separator, also known as the gravity separator or air table, makes a highly sensitive dry separation on the basis of one of the three particle characteristics – density, size or shape.

Adjustable cutting fingers, positioned to make the final selection between separated fractions, direct each fraction to a separate discharge spout. Gravity separators are generally available in two basic designs—rectangular-deck models and the more common trapezoidal-deck models. Rectangular-deck separators are recommended strictly for …
The flocculation that takes place in the central feedwell of the thickener plays a crucial role in the coal-slurry thickening process, which is not only complex but also largely influenced by the flow characteristics. A coupled computational fluid dynamics–population balance model (CFD–PBM) was used to model the complex …
Thickener efficiency influences the potential capacity of the entire refinery. Upgrade of the feedwell design is one of the means to enhance the performance and improve slurry separation providing for the better mixing of the slurry with reagents to stimulate residue settling.
