Bulk materials handling for the production of primary aluminium. How you can safeguard reliable materials handling from raw materials supply through to elec- trolysis - with a universal approach. compounding & extrusion >materials handling >service te^. confidence through partnership

03 >>Why you need what we convey. Aluminium has a bright future. The growing number of possible a ­ pplications for this promising material has resulted in higher quality requirements, and demand is on steady increase. For the production of primary a ­ luminium, reliable and economical raw materials supply is the first main requirement to be met – irrespective of whether you are modernizing an existing plant or designing a new one. We convey alumina reliably, gently and economically, from raw materials receiving through all stages of handling up to electrolysis. This is what you need to safeguard...

>>Why we deal with complexity in an individual way. The tasks involved in the design and implemen­ tation of a plant from project planning through to i ­nstallation, and also of individual process ­ tages for s handling alumina and petroleum coke, are extremely complex. However, our experts master these with ease. With their experience, pragmatic approach and our innovative technical developments, they make sure that the optimum solution is elaborated for you in the shortest possible time. You can rely on us to further your complex interests with ­ ailored t concepts.

Alumina PetCoke Alumina As soon as we have worked with you to clarify the specifications and requirements of your plant or individual process stages, we pull out all the stops to make our know-how in handling alumina and petcoke work for you. As a result you can be sure that you get just what you need to produce primary aluminium to a consistently high quality standard – a plant which is designed fully in line with your specifications. This already starts with vacuum ship or wagon unloading with track-proven Hartmann know-how, continuing with intermediate conveying, in-plant storage and in-plant...

Intermediate Conveying >Raw Materials Receiving Why we enjoy an unloading challenge. Because time is money, and this is also very true when it comes to alumina and petcoke unloading. As large quantities of alumina and petcoke are required for aluminium production, the raw materials are either supplied by ship (A) or rail wagon (B). Short ship lay times during unloading are a most important cost-cutting factor. This is something we can guarantee, and at the same time ensure gentle and reliable unloading of your product. The pneumatic ­ operion C ship unloader features leading-edge technology backed...

Intermediate Conveying Why we overcome any distance quickly and directly for you. After unloading the alumina and petcoke, we transport it as quickly and gently as possible to the silos with pneumatic or mechanical conveying systems. To ensure high-quality transport, we select the most suitable conveying mode from our uniquely comprehensive portfolio and customize it to suit site conditions and requirements. Depending on the requirements and the individual ­ ituation, s we use Coperion’s own pneumatic conveying technologies and also trough chain conveyors. For vertical transport we use either...

In-Plant Storage Alumina PetCoke In-Plant Conveying Distribution To Electrolysis Cells

Intermediate Conveying >In-Plant Storage Why powders can be buffered. When charging and discharging alumina silos and also during storage, it is particularly important that a regular particle distribution is maintained. When handling petcoke the main challenge is to evacuate the product reliably. Our know-how guarantees reliable processes for both raw materials. To prevent segregation of the alumina during feeding and discharge, we collaborate with IBAU HAMBURG to implement an effective anti-segregation system. On the silo roof the alumina is distributed from a central transfer point through...

In-Plant Conveying Distribution To Electrolysis Cells

Intermediate Conveying >In-Plant Conveying Why our gentle systems ensure raw materials ­ uality. q Gentle transport and therefore low particle degradation in the alumina enables stable operating conditions and a constantly high quality in the cells. No matter how far your storage silos are from the smelter – your product will always reach the “hot spot” in best form. A number of different conveying technologies are at your disposal. The principle is, however, the same for pneumatic, mechanical or truck transport. Coperion has the know-how 13 | Maxi CONVEYor 14 | Dense Phase CONVEYING – DUROSTAT...

Intermediate Conveying >Distribution To Electrolysis Cells Why slow speeds boost production. With our D ­ URODENSE system we offer a very gentle ­ rocess p for charging the electrolysis cells. Slow, continuous, reliable and self-regulating – these are all ­ dvantages a which really count during this process stage. Our D ­ URODENSE ticks all the right boxes as a perfected technology. With its low alumina flow ­ elocity, the DURODENSE system v prevents a scaling effect, providing a sound basis to ensure that primary aluminium manufacturing is reliable and continuous. This system is self-regulating...

17 >> Why powder is not just powder. Professional handling is essential – especially when transporting raw materials in powder form. We have the necessary experience and know-how on our side. Our technical centre holds an archive of the properties of more than 10,000 bulk materials with all their conveying characteristics. More are added almost daily, as our customers trust us with their new developments and innovations. As a result we can show you the optimum solution for all conveying and handling stages for your production line. In addition, we have also installed more than 8,000 ­ aterials...
