Calculate Slurry Flow / Volume

calculate slurry flow volume

An example of how you can calculate the slurry flow/volume of a given SG, %Solids and Tonnage. EXAMPLE: 3,400 tons of dry solids is processed in 24 hours in water with a specific gravity of 1.0 and the concentration of solids by weight is 33% with the solids having a specific gravity of 3.7 then … Read more

Percent Solids to Specific Gravity Conversion of Slurry

calculate slurry SG

Here is the formula for specific gravity of a slurry, S is: S = specific gravity of slurry Si= specific gravity of liquid phase Ss= specific gravity of solids phase Cw = concentration of solids by weight Cv= concentration of solids by volume EXAMPLE: if the liquid has a specific gravity of 1.2 and the concentration … Read more
