One possibility is to remove the crud in the extraction stage from the process. For this purpose, GEA Westfalia Separator Group has developed special 3-phase decanters designed for the tough requirements of the product. In an initial stage, these decanters separate the emulsion which has previously been drawn off from the tank into solids, aqueous phase and solvent. Water and solids are disposed of. The organic phase, however, is enriched with activated clay and is then passed through a 2-phase decanter. 4 PLS Clarification – the Most Innovative Alternative PLS clarification with nozzle-type separators from GEA Westfalia Separator goes one step further: it does not permit crud to form. In addition to the traditional crud and clay treatment Nozzle-type separators from GEA Westfalia with decanters, GEA Westfalia Separator Group also Separator Group reliably remove those insoluble offers an alternative process: PLS clarification with particles.

However, the operations can only be carried out successively. and 2-phase processes • Continuous recovery of the organic components • Permanently “cleaned” extraction agent 2-phase decanter The repeated use of extraction agents leads to a deterioration in effect as a result of ion saturation of the radicals. In order to “clean” the radicals, absorption agents such as clay are added. The suspension to which clay has been added is fed into the decanter, where it is split into two phases. In 2-phase decanters, the clay is removed from the suspension so that the customer receives a virtually solids-free clarified organic phase. The solid-wall bowl of the 2-phase decanter illustrated in the diagram has a cylindrical section for efficient separation and clarification of the suspension as well as a conical section for efficient dewatering of the separated clay. The product is continuously fed into the rotating bowl via the feed tube and is accelerated to bowl speed. The clay sediments on the interior wall of the bowl due to centrifugal force; it is then scraped off by the armour-plated scroll and conveyed to the solids discharge. The level of liquid in the bowl and thus the lengths of the clarifying and dewatering zones can be varied depending on the feed conditions. The organic 11 0-point drive The 0-point drives are part of the standard program. They feature a very simple design and are therefore cheap to purchase and operate. 0-point drives are used when the solids volume is constant, the solids are easy to convey and the requirements regarding the residual water content of the solids are not very stringent, in other words, bowl and differential speed regulating facilities are not necessary. This is because alteration of the differential speed can only be achieved by changing the gear transmission or the bowl speed. Exchangeable pulley drive The exchangeable pulley drives are also part of the standard program. They are also very cheap to purchase and feature a simple design. The input shaft of the drive is set in motion by the main motor via a second belt drive. This generates the differential speed as a function of bowl speed and gear transmission. This can be easily changed by replacing the belt pulleys. 2-motor drive The 2-motor drives enable the differential speed to be regulated cost-effectively under good operating conditions; wide regulating ranges are possible. The secondary motor sets the input shaft of the gear in motion and generates the differential speed as a function of bowl speed and gear transmission. The differential speed can easily be regulated by changing the motor speed. 2-motor drives are used whenever solid volumes fluctuate significantly, when solids are conveyed under difficult conditions and when particularly stringent requirements are applicable with regard to residual water content. Hydro-drive The hydro-drive works in a way which is similar to that of the differential gear drive. The difference is to be seen in the design.Instead of the mechanical gear, a rotating hydromotor is installed; this is supplied with hydraulic regulation by a pump unit. Because the differential speed is proportionate to the conveyed quantity of oil, automatic regulation can be provided without any problem. 12 Innovative Drive Concepts for Decanters Flexible process management with simultaneous maximum availability are essential requirements for modern drive concepts. The variety of process engineering applications in also customer wishes determine what type of drive is which decanters from GEA Westfalia Separator Group used. In the case of decanters which are used in the are used requires different drive concepts.

The 2-gear drive and the differential gear drive have The requirements for the machine and process but therefore become established in practise. 2-gear drive The advantage of the 2-gear drive which has been developed and patented by GEA Westfalia Separator Group is the facility for regulating the scroll drive. The differential speed is adapted automatically and extremely precisely as a function of the scroll torque – and thus as a function of the solids content in the bowl. Accordingly, the solids are discharged from the bowl with a constant concentration and in an extremely dry state. 2-gear drives are used whenever the volume of solids is not constant, when the solids are difficult to convey and when very high requirements are applicable with regard to the residual water content of the solids. Differential gear drive The differential gear drive is recommended whenever it is necessary to automatically regulate the scroll speed in addition to regulating the bowl speed. This can be achieved by means of two gears. The secondary motor drives the central input shaft and generates the differential speed proportionally to its own speed. A second input shaft without any speed is connected to the housing. This means that the differential speed is not dependent on the bowl speed. Differential gear drives are used primarily in the lower range of the differential speeds. 13 Decanter Wear Protection – No Chance for Abrasion and Corrosion GEA Westfalia Separator uses highly resistant duplex steel and special armour-plating for all parts which come into contact with product. Crud treatment and recovery of organic components One possible solution is spray cladding, in which car- expose decanters to extreme material strain.

Nozzle-type separators discharge concentrated sus- The size of the bowl diameter and thus the number pensions continuously via nozzles which are installed of nozzles are linked proportionately to the potential on the periphery of the bowl. The product flows via concentration of the concentrate. The concentration the feed into the bowl, where it is separated into increases in conjunction with increasing throughput, concentrate (underflow) and centrate (overflow). The high initial concentration of the product, declining disc stack which is installed in the bowl increases the solids content in the discharge, small nozzle diameter equivalent clarification area and thus the perform- and a low bowl speed. ance of the separator. The task is to achieve a balance between these factors and the equivalent clarification area as a standard measure for the clarifying performance of the bowl, Product feed in order to make sure that the remaining solid content in the concentrate permanently meets the customer‘s requirements. With the online analysis facility which is offered by GEA Westfalia Separator Group and which is based Centrate on measurement of the concentration of the product upstream and downstream of the nozzle-type separa- Concentrate tor, it is possible to adjust the clarifying performance of the centrifuge very precisely. The figures resulting from the concentration measurements are used for automatically carrying out adjustments to the feed capacity and the concentrate recycling.

The advantage of this solution is that the electrolyte bath has to be replaced much less constantly high yields • Explosion protection design (ATEX compliant) frequently – with a positive impact on operating and disposal costs. This separator is equipped with a self-cleaning disctype bowl. The solution itself is separated in the disc stack into a light and a heavy liquid phase. At the Product feed same time, the solids which accumulate in the bowl space are removed by centrifugal force. At regular intervals, the bowl opens automatically via the piston Aqueous phase valve and ejects the solids. The light liquid phase (solvent) flows towards the centre of the bowl through the disc stack, and is discharged via drill holes in the hood. The heavy liquid (aqueous phase) flows to the Solvent periphery of the bowl via the separating disc, and is also discharged under gravity. The new generation of separators for liquid-liquid separation covers the entire range of possible capacities. They feature a high Solids motor performance and optimum dynamic qualities with low energy consumption. Further advantages are to be seen in the high reliability, simple operation and low maintenance costs. The process is suitable for recovering copper, nickel, cobalt and uranium. All advantages at a glance: • Self-cleaning bowl for automatic discharge • Hydrohermetic product feed for gentle treatment • Flexible adjustment of the separating zone for maximum separating efficiency of the liquid phases • Direct drive for optimum energy efficiency and low service costs 17 Drive Concepts for Separators Different drive concepts are also available for the separators. Two drive concepts are in the programme: flat-belt and directdrive. Flat-belt drive In this solution, the motor power is transferred to the spindle by means of an antistatic flat-belt. Oil circulation lubrication ensures that bearings are continuously lubricated. This also means that the separator does not have to be shut down for an oil change. Compared to the gear drive, which is still used in older models, the motor power is transferred with up to 10 % lower power losses. The belt itself can be replaced quickly and in a servicefriendly manner without the bowl or motor having to be dismantled beforehand. Direct drive system The direct drive is an example of intelligent simplification in separating technology. Wherever the upper limit for gear loads has been reached or belt drives are undesirable, our separators with direct drive permit virtually loss-free power transmission. This boost in performance simultaneously reduces the costs of energy, wear, maintenance and space. The required power is transmitted directly to the bowl spindle by a 3-phase AC motor with frequency converter control via a torsionally elastic clutch. The spindle assembly is likewise supported by rubber-metal cushions. This makes possible low-vibration running at high bowl speeds. At a glance: • Extremely space-saving design • Avoidance of housing deformation • High performance input • Low maintenance requirement 18 Rotary Brush Strainers and Wear Protection Upstream rotary brush strainers and a special coating for components which are at risk protect the separators against clogging and abrasion. Excessively large solid particles can clog the nozzles of the separators. This is reliably avoided by installing a rotary brush strainer from GEA Westfalia Separator Group upstream. The product is fed into the strainer insert through the inlet, and flows through the strainer in the chamber to the discharge. The coarse solids are retained and scraped off the interior of the strainer by the rotating brushes. They fall into the conical base, from which they are discharged manually from time to time or automatically through the solids discharge. Special coating against abrasion In order to ensure that maximum performances are permanently achieved, the nozzle-type separators are also equipped with a special wear protection against abrasion. This solution comprises coated wear plates as well as a coating on the distributor bottom and the bowl bottom. At a glance: • Upstream rotary brush strainers prevent clogging of the nozzles • Reliable protection against abrasion • Maximum separation performance in the overall process • Maximum maintenance intervals Fine particles Product feed Coarse particles 19 Separators from GEA Westfalia Separator – Convincing Right Through to the Smallest Detail Machine portfolio >> GEA Westfalia Separator Group supplies a complete machine portfolio (capacity up to 500,000 l / h) with compatible hydraulic performance parameters / performance reserves – the right separator for every customer requirement Modular total concept Operating the separators >> Customized solutions and delivery as required by customers >> Personnel-friendly operating of the separators and, if required, 100 % remote-monitored operation possible, thus enhancing operational reliability and availability >> Combination of maximum robust nature and reliability >> Low water consumption as no cooling necessary for the drive and Special materials Discharge and feed design the slide ring packings >> All product-contacting components, hood, solids chute and frame coating can be supplied in application-specific materials, resulting in optimum resistance and product neutrality >> Feed design can be adapted to product requirements >> No product mixing / contamination possible in the discharge line.
