Thickeners

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...
