Benefits

  • Broad size range
  • Capacities from 58 STPH to 985 STPH
  • A relatively wide range of coal sizes can be cleaned in a wide range of cyclone sizes
  • Several ceramic lining options from 1" to 1.5" thickness are available to optimize wear life
  • Extremely efficient cleaning device using finely ground (-325 mesh) magnetite and water as the "media".

 

Krebs Heavy Media Hydrocyclones look like classifying hydrocyclones but they are made specifically to clean coal. A gravimetric separation takes place due to the buoyancy effect of the media forcing the lighter coal solids to the center of the hydrocyclone where they are transported upward and through the vortex finder. The dense mineral matter spirals toward the apex and exits through that orifice.

  • Media density primarily determines separating gravity.
  • 1" to 1.5" ceramic lining is critical since high ash "refuse" is very abrasive.
  • Pressure should be kept low to mitigate classification of magnetite particles.
  • Heavy Media Cyclones are usually operated in a near-horizontal orientation allowing for large apex sizes to be used for refuse removal.
  • Cyclones 30" diameter and larger utilize a patented ceramic "acceleration wedge" to adjust capacity and G-forces
