What we offer

Enhance your fine-particle separation with patented technology

Our gMAX technology minimises turbulence and maximises tangential velocity to give you better performance.

gMAX® patented technology

We used computational fluid dynamics (CFD) analyses to create a design that features more sharply angled upper cones and longer, angled lower cones. This combination maximises 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.

With gMAX, you get cyclones that work more efficiently at higher capacities and with less maintenance. Enjoy increased throughput
at a lower operating cost.

gMAX® large cyclone manifold

Our design engineers create custom manifolds for your specific applications. Our manifold designs permit convenient removal of any cyclone without disturbing the other cyclones or disassembling the manifold system. Various materials of construction are used to ensure compatibility with the slurry. Learn more about our manifolds.

Key benefits

Higher performance cyclone; lower capital cost

Finer, sharper separations at high capacities: A combination of more sharply angled upper cones, followed by longer, angled lower cones maximises tangential velocity in the upper part of the cyclone and 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 in the overflow.
High efficiency and feed density with fewer cyclones: The gMAX Cyclone inlet and cylindrical sections operate at a higher capacity. Fewer cyclones are required to process your feed with the high performance that was previously only achievable using many small diameter cyclones at a much higher capital cost.
Low cyclone inlet pressure and extended wear life: The advanced design of the gMAX Cyclone reduces turbulence at the inlet and the misplacement of material to the overflow to extend your liner wear life. Premium ceramics in the lower section of the cyclone also boost overall wear life, increasing the intervals between complete cyclone rebuilds.
Easy retrofit installations: Our gMAX is easily retrofittable into existing installations to boost your throughput and produce finer separations.

Product features

Design for mining and industrial cyclones

Inlet head design
Our inlet head improves upon what was the preeminent design for more than 30 years. The outer wall involute classifies the feed solids before they enter the inlet head. Then the feed encounters an improved vortex finder and top cover plate liner. These improvements reduce the misplacement of material to the overflow and dramatically increased wear life.

Cone design
Our upper cones have a sharper angle than other cyclones on the market, and the lower cones have a longer angle. This combination increases the tangential velocity in the upper part of the cyclone and the residence time in the lower section. In the end, you get a substantially finer separation, with fewer fines in the underflow and less coarse material in the overflow.

Wear testing

We tested our CFD predictions by applying layers of paint in different colours 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 laboratory, and pumped slurry through them. At the end of the test, the wear patterns showed a dramatic reduction in wear on the gMAX cyclone inlet head liner.
