Hiller Decanter Centrifuges for Mining, Tunneling & Drilling Fluids

 

Mineral industry

Centrifuges are used all over the world to prepare mineral suspensions. Hiller decanters are ideally suited to hydrometallic processes, such the extraction of gold, silver or nickel. The processing of industrial minerals such as calcium carbonate, kaolin or titanium dioxide is also optimally carried out using Hiller technology. The dewatering and classification of mineral sludges is a complex issue, and requires special designs. Hiller high performance decanters have been developed and optimised rigorously for these applications.

Mining and tunnel construction, drilling fluids

Due to globalisation, the expansion of road networks is increasingly gaining in importance. Hiller decanter centrifuges are increasingly used for solids/liquid separation in tunnel construction, both for shield tunnelling technology, and for microtunnelling and tunnel dewatering. A further application is the processing of drilling sludges in the geothermals field.
