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

In principle, the hydrocyclone is a solid bowl centrifuge of “slim” design. lt can be compared with a high-speed tubular centrifuge but also with a long-tube decanter. In the case of the hydrocyclone, however, the body is stationary. Rotation is here initiated by the flow arising from the tangential feed under pump pressure. The figure shows the rotational flow in a primary vortex, which is directed downwards, and the internal secondary vortex directed upwards. Whether the tube rotates, as for centrifuges, or only the fluid in the stationary cyclone, the result is the same: the action of centrifugal forces in the circulating suspension in both cases leads to segregation due to a radially outward sedimentation.

Design features and advantages

  • Optimum separation characteristic at varying operation parameters
  • Long life time of hydrocyclones due to appropriate selection of material for each application
  • 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
