MORE THAN A MACHINE:

DECANTERA centriuge decanter; consists o a solid cylindirical bowl rotating at high speed, a scroll rotating at the sameaxis with a slightly dierent speed, a drive group adjusting the speed dierence and the body which carriesall the rotating elements.Liquid and suspended solids are ed along the centre line to a distribution room within the bowl and thenaccelerated into the bowl by centriugal orce through the eeding point. This centriugal orce then causesthe suspended solids to settle and accumulate at the bowl wall.

Sludge cake is discharged by scroll rom the conical part meanwhile claried liquid ows back along the

bowl and is discharged through the cylindirical end o the bowl by plates which can adjust the level oclaried liquid.

Centriuge decanters are applied or separation o liquid mixtures, separation o solid-liquid mixtures,dewatering, thickening, classication o solid-liquid mixtures and extraction o components.

RIGHT ENGINEERINGSOLUTIONS

Bowl GroupThe bowl is cylindrical / conic and rotates at a pre-adjusted speed most appropriate

or the application. Suspension rotates at processing speed along with the bowland orms a concentric layer at bowl perimeter. Solids available in the suspensionaccumulate at bowl perimeter with centriugal orce. The length o the cylindricalsection o the bowl and the conic section angle are adjusted as per the speciccondition o each application.

Spiral GroupSpiral rotates at a slightly dierent speed than the bowl and conveys the accumulatedsolids to the end o the conic section o the bowl. I the physical properties o themixture change, it is possible to support DESS Decanters with a dierent spiraldesign or by modiying the existing spiral. Spiral step or single or dual wound spiralcongurations are signicant design variables.

MaterialHAUS uses high quality stainless steel on all suraces that the processed materialcomes in contact with.

Wear ProtectionDESS Decanters oer a wide range o wear protection products to be applied onmany areas where they are utilized:

Tungsten Carbide coating with plasma sprayCeramicSintered Tungsten Carbide plates

PolyurethaneWear protection parts are in-place replaceable in order to save on maintenance costso applications where high abrasive products are processed.

Bearing and LubricationSpecial selection and order o bearings ensure long machinery lie and exceptionalreliability. Central lubrication system delivers grease or oil to the bearings. Thelubrication system changes depending on the operation mode, e.g. sectional orcontinuous operation mode and depending on the automation level o the wholesystem.

Leveling Plates Treated liquids ow over the leveling plates and move orward to the end o thecylindrical section o the bowl o which theyll be delivered to. Easily adjustablesensitive leveling plates enable the pool depth o the bowl to be adjusted precisely.

The liquid overowing rom the plates is extracted with gravity rom central outletreservoir.

Constant Speed Drive System

This system has low investment costs due to very simple design. Thisdrive system is used when the solids amount is constant, the solidscan be conveyed easily and the amount o moisture in the solids is notcritical, which means it is not necessary to adjust the dierential speed.

Dual Drive System

Dual Drive provides dierential speed to be adjusted in a wide range.Second motor drives the gearbox input shat and makes the dierentialspeed as a unction o bowl speed and gearbox rate. Required speed

is adjusted when the solids amount is variable noticeably, it is hard toconvey the solids and it is important to minimize the amount o waterhold in the solids without any human intererence. Dierential speed isadjusted automatically and very precisely as a unction o scroll torque.

The system is supported by the sotware developed by HAUS.

Driver System with Hydraulic Motor

Instead o a mechanical gear, a rotating hydraulic drive is assembled andthis motor is supported with hydraulic regulation. Automatic regulationcan be done with no problem because the dierential speed is directly

proportional with the amount o the oil transmitted. Driver system withhydraulic motor is used when the solids amount is variable, it is hard toconvey the solids and it is important to minimize the amount o waterlet in the solids.

Control and AutomationAutomation o DESS Decanters enables personnel- ree operation. Inaddition to the operating variables o the decanter, below unctions canbe also monitored rom main control room:

Bearing and lubrication temperature

Bearing and main structure vibrationGear torque or the control o dierential speed with respect to torqueLeakage control or isolated systemsTurbidity control or centrate monitoring


Drive SystemsHAUS applies advanced engineering techniques to accelerate the decanters to high speeds in sae.

One o the most important key actor or decanters is the dierential speed. Dierential speed determines the amount omoisture hold in the separated solids and the clarity o the centrate. This speed can be adjusted according to the required productcharacteristics. Drive systems which run to determine this speed are given as below:

ADVANTAGES OF THEDECANTER

Decanter provides the advantage o high efciency operation compared to traditional separation systems. It was necessary todevelop continuing systems in order to reduce the increasing company costs and or the growing industry to be able to adjustitsel to the acquired achievements.

Application exibilityDecanters provide practically high efciency results undeructuations at product inlet, dierences in process conditions

and even at dierent characteristics o various products. Thiscapability enables reliable and regular operation.

Operational conditionsAppropriate body designs and isolation systems can beapplied or steam proo or pressurized processes between 0-8bars. Tailor made designs and machinery designs are availableor cleaning in place (CIP) systems to be used in extremelylow and extremely high temperature conditions, explosiveatmosphere standards and hygienic environments.

AutomationOperation o the decanter became ully automatic with

the use o modern devices and control units. The ability tocontrol whole acility rom a central control room enables thedecanter to be operated with no personnel.

Corrosion and wear protectionProcess specic materials highly resistant to corrosion andabrasion are used in decanter manuacturing.

Low space requirementWith its excellent design and high processing capacity, thedecanter requires a lot less space compared to alternativesystems.

Easy installationIt is possible to install the decanter easily and quickly thanksto its design and all the required unctions integrated insingle unit. Low vibration levels and active support systemo DESS decanters eliminate complex and expensive baseconstruction. Auxiliary equipments and connections are notneeded.

Personnel saetyClosed design o the decanters and the availability o high-tech saety systems ensure high saety or the operator andthe maintenance personnel.

Decanter centriuges provide ideal solutions or many dierent processesand industrial applications. As a result o studies perormed jointly with ourcustomers and research groups, designs optimizing the whole manuacturingprocesses are developed and manuactured or various applications.Besides general directives, there are no routine calculations to determine theequipment or a specic separation process. In many cases, the knowledge

and experience o HAUS engineers shall be sought or optimum technicaland economic solution. A study to be perormed jointly with the laboratoryand eld tests with mobile units will provide the best solution.

Product samples and the required data related to the process are acquiredand assessed at HAUS laboratory and the optimum machinery or systemsolution is oered. Moreover, onsite tests are perormed by our mobile unitswhich can be adjusted or dierent capacities and processes.

Not only separation characteristics o the product will be analyzed, but alsothe abrasive and corrosive properties o the inlet products will be analyzed.Particle size distribution, density and viscosity measurements will be done

as well. All these procedures are eected to choose the most appropriatemachine or the specic application.
