AKA-SPIDER are annular distributors, combining several hydrocyclones together in order to reach a requested process throughput.

Principle of operation

The hydrocyclones are connected to an inflow chamber (feed chamber) which is fed with the necessary amount of slurry at a calculated pressure. Each hydrocyclone is charged with the same pressure. The hydrocyclone overflows will be collected in an overflow tank, and the underflows in a separate underflow chute.

Design features and advantages

  • Homogeneous and equal pressure distribution of the suspension on every hydrocyclone in operation
  • Equal flow distribution
  • Customized design
  • Available as annular or longitude distributor
  • Available with rubber liner
  • Reduced dead zone in the feed tank
  • Different kind of shut off valves (butterfly valves, flat valves, bottom angle valves)
  • Can be equipped with antiblocking filter AKA-STRAINER
