introduction for a thickener unit

Beginners guide to thickeners Outotec

16/06/2017· Inventory Introduction Thickeners accumulate solids to allow both the residence time and the bed pressure necessary to achieve dewatering. To establish this solids inventory it is necessary to operate with the solids feed rate in excess of the solids withdrawal rate for some period during startup, then at steady state operation, the solids feed rate should match the

Sizing and Operating Thickeners

02/06/2017· Thickeners are often operated to keep the interface height constant using a level control device or manual measurements of the sludge level. In this case, if the feed solids rate is increased from 10.0 to 11.1 metric tons/day, the operating point at steady state will move from point no. 1 to point no. 4.

Thickeners MIP Process Technologies Ltd

Introduction. Thickeners are used in continuous process applications where liquid solid separation by sedimentation is involved. Thickeners have three basic purposes: Concentration, or raising the density of a mixture of solids and liquids Clarification, which involves removing solids from the mixture.

Thickener Torque Rakes Drive

13/08/2015· A little earlier I talked about the rakes of the thickener, these are long arms that extend off of the bottom of the DRIVE SHAFT. As the shaft turns the rakes will sweep the entire bed of the thickener thereby applied Torque. Each rake arm is higher at its far end than it is where it joins the drive shaft. This is designed this way to give the ...

Rota Rake Thickener Graver

Rota Rake® Thickener The Graver Rota Rake® Thickener is a horizontal flow sedimentation and thickening unit for the efficient separation of suspended solids from liquids by gravity. Designed for maximum separation, positive sludge removal and complete overload protection, the Rota Rake consists of: 1.

How a Thickener Works

13/07/2016· The Dorr torq thickener is a new development in the unit thickener field. The raking mechanism is supported from a stationary central pier on which the driving motor and gear reduction are mounted. The feed may be introduced at the center through a launder suspended above the top of the liquid leavel or by means of a siphon feed through the ...

How to Size a Thickener Mineral Processing Metallurgy

08/03/2016· Calculating Thickener Area: Thickener area required is then cal­culated by applying above determined data in the following formula: A = 1.333 /R. A = Thickener area in square feet per ton of dry solids thickened in 24 hours. F =

Introduction to Cyclones

Typical Applications: ead of a thickener to prevent sanding out. Location: Gold, Base metals, Minerals processing plants. Typical Applications: Degritting water. Location: Water treatment plant, Water storage dams, Shaft settling dams, Foundry quench. What are the Advantages of a Cyclone? No moving parts so low maintenance,

Thickening Resource Book

Thickeners. A thickener has several basic components: a tank to contain the slurry, feed piping and a feed well to allow the feed stream to enter the tank, a rotating rake mechanism to assist in moving the concentrated solids to the withdrawal points, an underflow solids withdrawal system, and an overflow launder.

thickeners clarifiers MIP Process Corp

tHiCkener design MIP Thickeners and Clarifiers are designed to operate continuously for 24 hours per day. Process selections are based on test work coupled with our vast experience in the field of thickening. It is our belief that a thickener should not be designed on the limit since metallurgical operations are dynamic.
