Mining

Quarry and drilling sludges are generally considered complex to be treated, due to their high abrasiveness and density; they therefore require high performance centrifuges with high resistance to wear. In quarries the centrifuge is used ideally to de-water the sludge deriving from the extraction minerals, both for the final washing treatment of aggregates and recycling of waste construction material. Regarding horizontal and vertical drilling, the sludge to be treated, in addition to sand, can contain clay and silt, also suspensions of cement and bentonite, which must be separated from the other substances in order to be re-cycled in successive excavation phases or de-watered at the end of the process.
