How To Measure Activated Bleaching Earth Particle Size

If the mesh size is too smooth(mesh size >350);it would make the process of fultering in oil refinery jammed.

But if the mesh size of activated fuller's earth too rough(mesh size of <150);it will reduce the ability of activated bleaching earth to absorb color.

How To Compare Bleaching Power Of Fuller's Earth

Bleaching power of activated bleaching earth is depend on its surface area(M2/gram).Epuipment to measure suiface area is B.E.t Analyzer.(mStephen Brunauner,Paul Hugh Emmett,and Edward Teller was the founder pf this tool) Read More >>

How To Measure Acidity Of activated Fullers Earth

Acidity in activated bleaching earth is sulfuric acid that is still inside the powder.After activating process of fuller's earth,it is washed with water to clean it from sulfuric acid;but there is still a little amount sulfuric acid remaining in the activated fullers earth. Read More >>

How To Measure Bulk Density Of bleaching bentonite clay

Fuller's earth that too light will make refinery filtering process jammed;but activated bleaching earth that too heavy will reduce its bleaching power to decolerrize oil badly.Bulk Density also indicates whether mesh pf the fullers earth is too smooth or too rough.Ideal fullers earth bulk density is bettween 0.5 to 0.6 gram/ml.
