The superiority of Sharples, Pennwalt and Tomoe Super-D-Canter is determined by the following factors. Super-D-Canter operates on the centrifugal sedimentation process. The high sedimentation efficiency and torque capability enables the Super-D-Canter to absorb feed variations more effectively than other types of centrifuge or separation equipment. To get started finding Sharples Centrifuge As 26 Manual, you are right to find our website which has a comprehensive collection of manuals listed. Our library is the biggest of these that have literally hundreds of thousands of different products represented.

Continuous Solid-Liquid Separation

Solids are continuously separated from the liquid phase by the application of centrifugal force ranging up to 3000 times the force of gravity, efficiently and economically. A characteristic feature of the Pennwalt Super-D-Canter Centrifuge is the cylindro-conical bowl containing within a helical/quasi-axial screw conveyor of matching profile that rotates in the same direction but at a slightly slower speed with respect to the bowl.

Extremely flexible Separations Tool

Handles slurries with a wide range of solid particle sizes from 5.0 mm to a few microns
Handles slurries with insoluble solids content from as low as 0.5%w/v to as high as 55%w/v.

Wide ranging, process specific applications of Pennwalt Super-D-Canter Centrifuge encompass:

Clarification of liquids.
Dewatering or de-liquoring of insoluble suspended solids.
Thickening or concentration of insoluble suspended solids.
Classification of insoluble solids suspended in liquid.

Economical Operation

Pennwalt Super-D-Canter Centrifuge has polymiser features, wherein the feed zone & conveyor flights are modified to reduce the floc breakage and minimise conveyor turbulence in the pool. These features result in considerably reduced dose of polymeric flocculants. In addition there is a substantial economy of space, power and labour required in the operation of the Pennwalt Super-D-Canter Centrifuge in comparison with alternative solid-liquid separations equipment.

Stainless Steel Construction designed to resist corrosion

Carbon Steel corrodes, leading to unbalance, high maintenance costs, long downtimes. Therefore the principle elements and stressed rotating components of Pennwalt Super-D-Canter Centrifuge are machined from quality centrifugally cast Stainless Steel.

Designed to resist abrasion

Sintered Tungsten Carbide Tiles positioned on the flights of the Pennwalt Super-D-Canter Centrifuge scroll (conveyor) outlast conventional hard surfacing systems many times over in any environment.

BD Feature

This makes slimy and gelatinous sludges SCROLLABLE. The BD feature allows the Super-D-Canter to operate at Ultra-Deep pond settings that compact the solids and creates hydrodynamic buoyancy that assists the scrolling and the discharge of slimy sludge. The insoluble solid contents are typically 1/2% - 2% in the feed slurry which are thickened to 6%-12% and discharged in the slimy cake.
3-Phase:
This is a Pennwalt Super-D-Canter Centrifuge which is designed to give three separate product phases such as water, Oil, and Cake Solids. Applications encompass Olive Oil, Fish Oil, Fish Blood-Water, Slop Oietc.
Often, one or both liquid phases need to be further polished on the high-G Tubular Bowl Super centrifuge.

Sterile Features

For Pharmaceutical, Biotechnology and Food Industries, the Pennwalt Super-D-Canter Centrifuge can be provided with Sterilisation-in-place (SIP) and Clean-in-Place (CIP) features.

Safety Features

All electric drives are provided with enclosures of Ingress Protection (IP) ratings selected for safe operation as per process requirements.
The Pennwalt Super-D-Canter centrifuges are designed and featured for operational safety with Inert Gas (N₂) purging to be provided by the end use customer, when operated with feed slurry containing a flammable and/or explosive solids or liquid phase.

Performance :

Four crucial factors govern the separational performance of Pennwalt Super-D-Canter centrifuges.

Centrifugal force required to sediment the solids.
Appropriate setting of the pool depth to achieve the required centrate liquid clarity.
Control of differential speed between the bowl and scroll, to convey the solids and obtain appropriately low cake moistures.
Hydrodynamic design of the conveyor to minimise turbulence.

In specifying a Super-D-Canter centrifuge, for a particular application, Pennwalt also considers other design features such as:

The pitch of the conveyor flights.
Number of Leads of the Conveyor.
Special Rinse or Floc Feature.
Feed zone design.
Beach angle.
Beach Internal Surface Profile.
Bowl Internal Surface Profile.
Torque Sensing and Over-load Protection.
Back-Drive or Eddy Current Brake for control of Differential Speed.
Casing Enclosure design.
Abrasion Protection with Tungsten Carbide Tiles or Stellite Hard Surfacing of the Conveyor.
Material of construction.
Sedimentation enhancing features and choice of polyelectrolyte flocculants.
Safety Featured casing and guards.

The correct combination of such features ensures the desired separational performance with operational safety for a given application at minimum cost. Operation at High 'G' force is an inherent design feature of the Pennwalt Super-D-Canter and provides flexibility to the user. The centrifuge can be operated at an optimum speed to suit the particular application. The Pennwalt Super-D-Canter can be operated at low, intermediate or high speed without the constraints of mechanical design, which can be optimised and tailored to suit each application.

How super centrifuge works

Sharples Centrifuge Manual

This sectional view of a Super-Centrifuge shows the application of centrifugal force to a mixture of two immiscible liquids containing some suspended solids.

Sharples P3400 Decanter Centrifuge Specs

The mixture continuously enters the Super-Centrifuge through an inlet feed nozzle at the base of the machine, into the hollow cylindrical rotor. Rotors have been designed and engineered to rotate at 17000 r.p.m. and generate centrifugal force of upto 20000 times the force of gravity.

This force separates the two liquids according to their specific gravities into concentric cylindrical layers, and the solids are deposited inside the rotating bowl against the rotor wall.

The separated liquids are continuously displaced upwards by the incoming mixture and continuously discharged through their respective outlet ports at the top of the rotor. The layer of accumulated solids that builds up on the inner diameter of the rotor wall is cleaned out batch-wise for which the super-centrifuge is shut down when it is filled up to the rotating bowl’s limiting solids holding capacity and the rotating bowl is removed for cleaning.

Pennwalt Sharples Centrifuge Manual

There are, however, many applications where only the removal of suspended solids from a single liquid is required. Super centrifuges for such applications are called Clarifiers and are often provided with only one set of discharge ports. Mylar Liners are optionally supplied and can be placed on the inner diameter of the bowl for ease of removal of insoluble solids deposited on the inner diameter of the bowl.
