How a Thickener Works - Mineral Processing & Metallurgy

How a Thickener Works Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full.

Thickeners - Types, Working Principle & Applications

In very simple words, a thickener is a machine that separates liquid from solids. It is defined as a method of continuous dewatering of a dilute pulp, wherein a regular discharge of a thick pulp takes place which is of uniform density, concurrently with an overflow of clarified solution.
