 gMAX® Series
The gMAX® Cyclone is an entirely new Krebs Cyclone — re-engineered from apex to vortex finder. The gMAX® Cyclone has the capability to produce finer and sharper particle separations using large high capacity hydrocyclones. The gMAX® Cyclone performance level was formerly only achievable using many small diameter hydrocyclones at a much higher capital cost.
The gMAX® Cyclone design includes new modern apex and cone designs that feature performance enhancing benefits as well as being constructed of one inch thick elastomer or ceramic composition for increased wear life. The hydrocyclone 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 hydrocyclones.
Through extensive testing, gMAX® performance has been proven in a wide variety of ores including iron ore, phosphate, coal classification and copper grinding circuits.
Some of the features and benefits of the gMAX® Cyclone design include the following:
- Finer, sharper particle separations at high capacities
- Fewer hydrocyclones needed for optimal performance
- Available in sizes ranging from 6 inch to 33 inch in diameter with 1 inch replaceable liners
- Operates at higher feed densities at the same separation size and/or lower hydrocyclone inlet pressure
- Operates at lower hydrocyclone inlet pressure
- Works with existing installations
The gMAX® Cyclone produces the performance you need with large diameter hydrocyclones while operating at lower pressures!
  
Features and Benefits
HARD ROCK MINING
For new installations the gMAX® Cyclone allows the use of fewer numbers of larger diameter hydrocyclones for grinding circuit and tailings applications. This reduces capital and operating expenses.
For existing grinding circuit applications, the gMAX® Cyclone can produce a finer separation potentially resulting in a higher circulating load and a finer overall grind and/or higher throughput. The gMAX® Cyclone can also produce a sharper separation resulting in less coarse material in the overflow and less fine bypass material in the underflow. The finer separation achieved by the gMAX® Cyclone can also allow for operation at a higher overflow density. Existing hydrocyclones can be retrofitted to the gMAX® configuration.
The gMAX® Cyclone will increase recovery of sand to the underflow in tailings applications.
COAL
For Raw Coal Hydrocyclones Upstream of Spirals
For new installations, fewer number of hydrocyclones are required since larger diameter gMAX® Cyclones can be used; usually 15-inch hydrocyclones are used for a D95 separation of 100 mesh but now a much fewer number of 20 inch gMAX® Cyclones can be used. This not only reduces cost of hydrocyclones, but also reduces complexity, size and cost of the manifold system for the hydrocyclones. In almost all cases there will be major space saving realized as well.
For existing installations of 15 or 20 inch hydrocyclones, more capacity can now be realized with the same quantity of hydrocyclones by utilizing larger vortex finders if gMAX® cone sections and apex assemblies are retrofitted. With standard hydrocyclone configurations, relatively small vortex finders are required to achieve a fine separation. This is no longer the case with the gMAX® design and extra capacity is easily gained.
For Clean Coal Hydrocyclones Downstream of Spirals or Water-Only Hydrocyclones
For new installations, this is a critical application where cleaned coal must be captured or lost to the refuse circuits. Several 15 or even 10 inch hydrocyclones are normally required. Again, 15 or 20 inch can now be utilized saving cost, space and distribution complexity.
For existing installations, the vortex finder size may be increased once the gMAX® cone sections and apex assemblies are added to gain more capacity.
Effluent Recovery, Refuse Dewatering and Dilute Media Classifying Hydrocyclones
In general all these hydrocyclone applications would benefit if a gMAX® design were utilized. Finer separations and/or more capacity are performance parameters that are usually not easily obtainable.
AGGREGATE
The gMAX® Cyclone will increase the recovery of sand in existing installations or allow for fewer larger diameter hydrocyclones in new installations.
FLUE GAS DESULFURIZATION
In new limestone grinding installations the gMAX® Cyclone allows the use of fewer numbers of larger diameter hydrocyclones. This reduces capital and operating expenses.
In new gypsum dewatering applications, the gMAX® Cyclone allows the use of fewer numbers of larger diameter hydrocyclones. This reduces capital expenses and can reduce the plugging problems associated with smaller diameter hydrocyclones.
The gMAX® Cyclone will produce a finer separation in existing installations. This can result in a finer overall grind in a limestone grinding application or allow more throughput. In a gypsum dewatering application the finer separation will result in more recovery of solids to the underflow.
