Hydrocyclones are important and economically viable Systems for the wet-mechanical séparation and classifying processes of ores and minerais. AKA-VORTEX are applied across the industry in various areas: sorting, desliming, dosed circuit grinding, solids recovery, classification.
Principle of operation
In principle, the hydrocyclone is a solid bowl centrifuge of "slim" design. It can be compared to a high-speed tubular centrifuge but also with a long-tube decanter. In the case of the hydrocyclone, however, the body is stationary. A rotation is initiated by the flow arising from the tangential f eed under pump pressure. The fluid is subjected to centrifugal forces, that lead to the c reation of a primary vortex, which is directed downwards, and an internal secondary vortex directed upwards. This leads to a segregation effect of the particles present in the fluid, due to a radially outward Sedimentation.
Design features and advantages
•Optimum séparation characteristic at varying operation parameters
•Long life time as per appropriate sélection of material for each application: highly wear-resistant polyuréthane, oxide- or SiC-ceramic, NiHard, titanium, diverse steels
•Simple in operation
•Fast and trouble-free changing of wear-parts
•Modular System is achieved by using simple connectors and adaptors (feed part, overflow and underflow nozzle)
•Low weight of single parts
•Easy adaption to changed operation parameters
•FDAapproval
•Heat résistant material
•Can be lined with high wear-resistant, Chemical- and corrosion-résistant materials (rubber, PU, ceramic)
Applications
•Minerais (e.g. Kaolin, Feldspar, Talcum, Chalk, Quartz, Gypsum, Bentonite, Zircon, Phosphate)
