ENG - Cavex G4 Spec Sheet.pdf

Outstanding efficiency, capacity, and long wear life. Cavex ® G4 hydrocyclones provide high capacity, economical and efficient classification, particularly in closed circuit grinding operations. Clusters of Cavex ® G4 hydrocyclones are also suitable for removing oversized grit from cement, clay, drill mud, effluent and other slurries. Classification occurs when coarse material reporting to the spigot is \ returned for further grinding, while fine material in the overflow progresses for further processing, such as CIP or flotation processing. Fines recovery and de-gritting of very fine solids requires small cyclones operating at higher than normal pressures. The diameter of the Cavex ® G4 hydrocyclone required to achieve this high pressure is determined by the particle size to be recovered. Total required throughput determines the number of Cavex ® hydrocyclones needed. An interchangeable inlet wedge allows the operator to quickly and easily vary the inlet size. This innovative feature provides the ability to fine-tune the Cavex ® G4 hydrocyclone performance without physically removing it from the process line, resulting in increased productivity and decreased downtime. The use of drop-in Cavex ® replacement wear liners, manufactured from Linatex ® premium rubber or high quality ceramics, reduces maintenance costs due to their excellent resistance to abrasion. Specific combinations of rubber and ceramics are available for lower cones and spigots, designed to provide an even wear pattern within the Cavex ® G4 hydrocyclone, enhancing its service life. Available sizes 100mm, 150mm, 250mm, 375mm, 500mm, 660mm, 840mm and 1200mm. Design features • Adjustable inlet size through interchangeable inlet wedge to optimise performance. • Replaceable drop-in Linatex ® premium rubber or ceramic liners. Applications • Mineral processing including closed circuit grinding, tails disposal, desliming and flotation or gravity concentration. • Coal Processing • Power / FGD • Industrial • Chemical • Sand and gravel • Limestone • Phosphate Above: The interchangeable inlet wedge (shown in purple) allows the operator to quickly and easily vary the inlet size to maximise performance.
