Beginners Guide to Thickeners

In high rate thickener (HRT) designs the rise rate or solids loading will dictate the required tank diameter for any given throughput In high compression (HCT) and paste (PT) applications the bed depth or the mass of solids in the thickener must also be selected to ensure the desired underflow density from the thickener is achieved...

The High Rate Thickener

Description The High-Rate thickeners became popular in the mid 1980's and are relatively newcomers to the sedimentation line of equipment As already discussed previously Thickeners are a major component in a plant layout and occupy large spaces which may be saved by introducing high-rate machin Furthermore, they are normally positioned far away from the center of the plant so to allow ....

Thickener Torque

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 bed a slope towards the centre of the thickener ....

Thickener Operation

Jan 26, 2015· Thickeners are designed to operate continuously with slurry/water consistently flowing into the centerwell with thickener underflow pumping balanced to maintain a mud bed in the thickener Key to thickener operational efficiency is the solids must be able to settle 2-4 times faster than the nominal water up flow rate...

Thickening

The control parameters used to maintain stable operation in high rate thickeners are underflow solids density, underflow withdrawal rate, flocculant dosage, solids inventory in the tank, solids feed rate, and mechanical torque limit restriction of rotating rake arm...

Conventional Thickeners

The Conventional Thickener , Conventional Thickeners are generally incorporated in heavy duty applications when the underflow density is high and substantial torques are required to convey the settled solids from the periphery to the central outlet for pumping away , Basically there are two groups of thickeners which differ in their rake ....
