Difference Between Clarifier and Thickener - 911 Metallurgist

May 15, 2017 ... The Difference Between a Clarifier and a Thickener is subtle as they will visually look the same. Fundamentally, thickeners and clarifiers are both used to settle solids which results in the separation of liquids and solids. Thickeners are used to concentrate solids, while clarifiers are used to purify liquids.

Thickeners - Mine Engineer

A thickener is a machine that de-waters slurry, separating the liquid from the solids. The solids' particle size range in thickeners is generally from 0.5 mm to a few microns. The finer the particle size, the slower settling and compaction rate. Actually, thickeners simply concentrate the solids, achieving underflow solids densities...
