Thickeners – MIP Process Technologies (Pty) Ltd

The introduction of polymeric flocculants gave an impetus to development of High Rate Thickeners. The result is now common use of the term "High Rate Thickener" which has been applied in all areas of industry. The characteristic features of a High Rate Thickener, which distinguishes it from a Conventional Thickener, are: Deeper feedwell

How a Thickener Works

Scraper blades or rakes, driven by a suitable mechanism, rotating slowly over the bottom of the tank, which usually slopes gently toward the center, move the material settled on the bottom to a central opening or discharge. ... Ltd. A water-soluble "H.V." grade used in the amount of 0.01 lb. per ton of ore increased the settling rate in …

DEWATERING * CONVENTIONAL AND HIGH-RATE THICKENERS

CONVENTIONAL THICKENERS. The objective of a thickener is to separate low-density slurries into a relatively clear liquid and a high-density slurry, or sludge.All thickeners depend on gravity to allow for settling fine solids. A thickener consists of a circular tank with a gradually sloping cone-shaped bottom with a discharge in the center.

How to Size a Thickener

Knowing how to size a thickener and determine the capacity required to handle a pre-determined tonnage of a certain pulp, by overflowing a clear solution and obtaining the desired pulp density of thickener discharge, depends upon the settling rate of that particular pulp. The settling rate of any pulp is easily determined by simple …
