How a Thickener Works Mineral Processing amp 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. 160The early methods of thickening employed plain, flat bottomed tanks into which the pulp was fed until the tank was full.

UNVEILING THE MYTH OF HIGH CAPACITY THICKENERS

UNVEILING THE MYTH OF HIGH CAPACITY THICKENERS. Concepts of Conventional and High Capacity Thickeners Conventional Thickener The name Conventional Thickener is used for equipments with short feedwells, where the flocculated pulp leaves the feedwell and enters into the settling zone of the thickener well above the sediment level. In the 1970s and 1980s, machines

CHAPTER 3 SLUDGE THICKENING Marmara 220niversitesi

CHAPTER 3 SLUDGE THICKENING Thickening is a procedure used to increase the solids content of sludge by removing a portion of the liquid fraction. To illustrate, if waste activated sludge, which is typically pumped from secondary tanks with a content of 0.8% solids, can be thickened to a content of 4% solids, then a fivefold decrease in sludge volume is achieved [1]. Thickening is generally

Clarifying and Thickening Neglected Unit Operations

28/08/2014018332Hydrometallurgical plants often have multiple thickener operations e.g. counter current decantation. Taking a desired 92.5% operating time with a total of 5 thickeners in series in the flowsheet means that each thickener has to be performing as specified 98.5% of the time ignoring all other causes of downtime and poor operation

Belt filter

The belt filter (sometimes called a belt press filter, or belt filter press) is an industrial machine, used for solid/liquid separation processes, particularly the dewatering of sludges in the chemical industry, mining and water treatment.Belt filter presses are also used in the production of apple juice, cider and winemaking. The process of filtration is primarily obtained by passing a pair

Pulp thickener is suitable for occasions with large processing capacity and low product concentration. It is mainly used for the concentration of concentrates and dewatering of tailings in ore dressing plants. Characteristics. There is a degassing tank in the high efficiency thickener equipment, which can eliminate the solid particles from adhering to the air bubbles and settle like a

Beginners Guide to Thickeners Outotec

Beginners Guide to Thickeners Beginners Guide to Thickeners. Thickening is a process where a slurry or solid liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water (or liquor in leaching processes). The driving force for the separation is gravitational, where the differences in

Thickening ANDRITZ

The performance of the gravity drum thickener is based on 50 years of pulp dewatering experience. The Drum Thickener PRS is a simple, cost efficient, and reliable filter for dewatering stock and broke ( and recycled fibers) in a consistency range of 0.55.0%. Features and benefits of the ANDRITZ Drum Thickener

How to Operate a Thickener Mineral Processing amp Metallurgy

The simplest use of a thickener in a metal mining operation is to get water out of a pulp for example, in a desert country where water is too valuable to be thrown away with the tailings. There you have a thickener treating the tailings and recovering some of the water to
