Designing Cyclones

Since 1978, our partner Minco Tech Australia has specialized in the design and supply of cyclones to the mineral processing industry. Many design components combine to ensure the performance of our Minco Tech classifying cyclone is maximized. Design parameters regarding inlet shape and area, vortex finder diameter length, body extension, cone angle and apex nozzle are of the most importance.

Other features including material selection and cluster design, ensure that the cyclone offered for any particular process has an individuality that guarantees efficiencies. Using this approach, Minco Tech Australia can optimize a system for each single project such as gold, nickel, diamonds and coal. Today Minco Tech design and provide the most efficient cyclones operating in the world today, endorsing our long term vision of true excellence.

Continuing Research & Development

Research and development rate highly on our priority list… in co-operation with national experts we are constantly testing our companies new theories and undertaking practical research both in the field and laboratories. Along with research and development partners, Minco Tech have been instrumental in cyclone technology to a world leading level. Cyclone performance predictions are accurately modeled with computer programs specifically developed classifying cyclones. These include the JK SimMet and Minco Tech computer programs. Further research is continuing to develop cyclone geometry and improve flow patterns within an operating cyclone. This work will enhance our computer performance modelling.

Ensure Maximum Efficiency

  • Feed sizing should be maintained as constant and consistent as possible.
  • Large changes of feed sizing, due to stockpile segregation, can reduce separating efficiency.
  • Feed sump design should also include fine product slumping which can result in large amounts of material collapsing and entering the cyclone feed pump causing feed rate, cut-point, product yield and product quality variations.
  • Cyclone body and apex nozzle wear should be regularly monitored and worn components replaced as quickly as possible. Temporary repairs can be undertaken using a range of wear resistance compounds. Prolonged use of such “stop gap” measures can have negative performance effects.
  • Improvement of separation accuracy can be achieved, in some cases, by a simple apex nozzle change.
