Revised Soil Classification System for Coarse-Fine ...

The fines threshold is F t h = 10 – 42 % in coarse-fine mixtures while the sand threshold is F t h = 47 – 70 % in gravel-sand mixtures. The threshold fraction F t h decreases when the relative size ratio R d increases, the liquid limit increases, the coarse grains become well graded, and the particle shape becomes rounder.

How to separate grit from activated carbon ...

2021-11-10  Shaking tables are an excellent method of separating coarse and fine sands from carbon. We treat small amounts of carbon, so we use an RP-4 table, but I imagine any Wilfley/Deister type table would work. The bulk of the carbon reports to the tailings port. Be sure and screen your middlings port as sometimes carbon reports there as well.
