Advanced hydrocyclone design improves fine coal recovery
Improve your throughput with reliable and long-lasting cyclones. Designed with your operational needs in mind, our innovative KREBS gMAX Cyclone has enhanced hydrocyclone geometry and materials of construction to provide you with finer, sharper separations.
What we offer
Improve fine coal particle separation with patented technology
The gMAX Cyclone is re-engineered from apex to vortex finder specifically for the coal industry. The high-capacity gMAX Cyclone will produce finer and sharper separations using large, high-capacity hydrocyclones. By improving your performance and availability, gMAX will also increase your productivity.
Optimum cyclone performance relies on minimising turbulence, while maximising tangential (outer edge) velocity. As a leading cyclone manufacturer, we designed our gMAX cyclone to focus on both of these important factors. 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.
The outer wall involute design entrance pre-classifies the feed solids prior to entering the main body of the cyclone. 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.
To eliminate cyclone housing corrosion, we now encase ceramic liners in rigid polyurethane, completely eliminating the need for steel housings.
Key benefits
Boost your productivity and efficiencies with gMAX Cyclone technology
- Minimises coarse solids misplacement to overflow
- The innovative gMAX inlet design provides finer and sharper particle separation at high capacities. The outer wall involute design entrance pre-classifies the feed solids prior to entering the main body of the cyclone. These improvements result in reduced misplacement of material to the overflow.
- Longer 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. Urethane encased ceramics provide external corrosion resistance ensuring maximum component wear life.
- Requires fewer cyclones for optimal performance
- The gMAX Cyclone inlet and cylindrical sections have been modified to minimise turbulence and wear, but still have the ability to operate at much higher capacity. The result is cyclone performance that was formerly only achievable using many small diameter cyclones, at a much higher capital cost.
- Operates at higher feed rates, achieving the same separation size
- gMAX Classifying Cyclones can handle 0.5-in (13 mm) top size at capacities up to 50 STPH (45 MTPH) per cyclone. It easily handles feed densities up to 15% solids maximum; underflow densities of 40% to 50% solids are normal for raw coal applications.

Cone design
Through the use of computational fluid dynamics (CFD) analysis, our gMAX Cyclone for coal classification design features an extended cylindrical body section, followed by 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. The result is a substantially finer separation, with fewer fines in the underflow and less coarse material bypass to overflow.
Specifications
Available in 6-in, 10-in, 12-in, 15-in and 20-in (150mm, 250 mm, 305 mm, 380 mm and 500 mm) diameters. The unique lower cone arrangement permits ultra-fine separations ranging from near 60 to 200 mesh and (0.250 to 0.074mm) D95 separation size and will increase recovery.
The gMAX features exceptional abrasion resistance through reaction-bonded silicon carbide ceramic in the lower cones, and nitride-bonded silicon and carbide ceramic in the upper sections. In the larger cyclones, the ceramic liners are encased with polyurethane with no steel housings to corrode. Available with cone angles of 10.5 or 20 degrees. The gMAX is fully retrofittable into existing installations.
