KREBS® Cyclone

Enhance Your Fine-Particle Separation with Patented Hydrocyclone Technology
Optimum cyclone performance relies on minimizing turbulence, while maximizing tangential (outer edge) velocity. The gMAX Cyclone focuses on both important factors, and the result is a cyclone that provides significantly advanced performance. In fact, the performance level reached by the gMAX was once only achievable using many small-diameter cyclones, at a much higher capital cost.

gMAX Cyclones: Higher performance cyclone; lower capital cost.

KEY BENEFITS:

Finer, sharper separations at high capacities:
A combination of more sharply angled upper cones, followed by longer, angled lower cones maximizes tangential velocity in the upper part of the cyclone while it provides a long residence time in the lower section. The result is a substantially finer separation, with fewer fines in the underflow and less coarse material bypass to overflow.

Retrofit into existing installations:
The gMAX is easily retrofittable into existing installations, to boost your throughput and/or produce finer separations for your operation.

Extended liner wear life:
The advanced design of the gMAX Hydrocyclone not only reduces turbulence at the inlet, but reduces misplacement of material to the overflow – reducing wear. Premium ceramics in the lower section of the cyclone also boost overall wear life, increasing the intervals between complete cyclone rebuilds.

Wear tests validate CFD predictions:
To validate our CFD predictions for reduced turbulence and wear characteristics on the gMAX inlet head design, we applied layers of paint in different colors to both the gMAX inlet head liner and a competitor’s outer-wall tangential inlet head liner. We assembled the components onto cyclones in our cyclone laboratory, and pumped and slurry through them.

The resulting wear patterns shows a dramatic reduction in wear on the gMAX inlet head liner as a result of the gMAX improved geometry.

Design for mining and industrial cyclones:

Inlet Head Design
The innovative gMAX inlet has an outer wall involute design entrance pre-classifies the feed solids prior to entering the main body of the cyclone. The inlet head of the gMAX also includes an improved vortex finder and top cover plate liner design. These improvements result in reduced misplacement of material to the overflow and dramatically increased wear life. By using premium ceramics in the lower section of the cyclone, we’ve boosted overall wear life, greatly increasing the intervals between complete cyclone rebuilds.

Cone Design
With the use of computational fluid dynamics (CFD) analysis, our gMAX cyclone design features more sharply angled upper cones, followed by longer, angled lower cones. This combination maximizes tangential velocity in the upper part of the cyclone. It also provides a long residence time in the critical separation zones of the cyclone’s lower section. The result is a substantially finer separation, with fewer fines in the underflow and less coarse material bypass to overflow.
