Kubis hydrocyclone is an important part of efficient solid-liquid separation equipment, which is made of high-performance polyurethane elastomer material casting, with the advantages of high wear-resistance, high strength, high elasticity, as well as light weight, corrosion-resistant, aging-resistant, easy maintenance and so on. It is widely used in petroleum mining, non-ferrous and ferrous and non-metallic mineral processing plant grading process in the grading operation and many other aspects of the slurry material desliming, dewatering operations, not only is the oilfield sand removal, mud removal devices, but also mine classification, tailing damming, coal plant coal slurry water treatment and coal slurry recovery and other important equipment important parts.
