Benefits

  • Finer, sharper particle separations at high capacities
  • Fewer cyclones needed for optimal performance
  • Available in sizes ranging from 2 to 33 inch in diameter with 1 inch thick replaceable liners
  • Operates at higher feed densities at the same separation size
  • Operates at lower cyclone inlet pressure
  • Can be retrofitted into existing installations

 

The Krebs gMAX is a new generation of cyclone, re-engineered from apex to vortex finder. The Krebs gMAX cyclone has the capability to produce finer and sharper particle separations using large, high capacity cyclones.

 

The gMAX cyclone performance level was formerly only achievable using many small diameter cyclones, at a much higher capital cost.

 

The gMAX cyclone design includes new modern apex, cone, and inlet head designs that feature performance enhancing benefits as a well as one inch thick elastomer or ceramic liners for increased wear life. The cyclone inlet and cylindrical sections have been modified to minimize turbulence and wear, but still have the capability to operate at much higher capacities than our competitor's cyclones.

 

Through extensive testing, the Krebs gMAX cyclone performance has been proven in a wide variety of applications including:

 

  • Copper Ore
  • Coal
  • Iron Ore
  • Phosphate
  • Gold
  • Molybdenum
  • Potash

Inlet Head Design

The Krebs gMAX inlet has improved upon the Krebs involute feed inlet that had been the state-of-the-art in hydrocyclones for over 40 years. The outer wall involute design entrance pre-classifies the feed solids prior to entering the main body of the cyclone. The upper part of the gMAX also includes an improved vortex finder and top cover plate liner design. These improvements to the inlet head result in less misplacement of coarse material to the overflow and dramatically increased wear life. This longer wear life for the gMAX inlet, combined with premium ceramics in the lower parts of the cyclone, will greatly increase complete cyclone repair frequency.

 

gMAX Inlet

 

  • The contoured, ramped inlet pre-classifies the slurry, reducing turbulence
  • Reduced turbulence minimizes course solids bypass to overflow

Cones

Through the use of CFD analysis, FLSmidth Krebs has designed the gMAX cyclone with sharper upper cones followed by longer angled lower cones. This combination maximizes tangential velocity in the upper part of the cyclone. It then provides a long residence time in the critical separation zones in the lower part of the cyclone. This results in a substantially finer separation with fewer fines in the underflow.

Apex

The KREBS gMAX apex maintains the same internal angle as the cone section above it. This results in high underflow density without driving coarse material to the overflow.
