Hydrocyclones are important and economically viable systems for the wet-mechanical separation and classifying processes of ores and minerals.
AKA-VORTEX are applied across the industry in various areas: sorting, desliming, closed circuit grinding, solids recovery, classification.

Principle of operation

AKA-VORTEX Hydrocyclone

In principle, the hydrocyclone is a solid bowl centrifuge of “slim” design. lt 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 separation characteristic at varying operation parameters
  • Long life time as per appropriate selection of material for each application: highly wear-resistant polyurethane, 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
  • FDA approval
  • Heat resistant material
  • Can be lined with high wear-resistant, chemical- and corrosion-resistant materials (rubber, PU, ceramic)
