SPHERE TANKS Deha Tech

Sphere storage results in the lowest land space for pressurized storage and offers lower costs for foundations, coatings, accessories, and piping than other options. A spherical tank is built with less pieces of material and has fewer welded connection points, which contributes to its strength.

Coal mills for all requirements Gebr. Pfeiffer

With petcoke and sponge coke, but particularly with the sphere-shaped petcoke, quite a different challenge needs to be met: despite the fineness of these feed materials, mill operation must be stable and smooth. And this is ensured by the geometry of the grinding elements of our coal mills which is particularly advantageous in this respect.
