Weir Minerals Africa on the Cavex CVXT hydrocyclone

Weir Minerals Africa says its locally-manufactured Cavex® CVXT tile lined hydrocyclone features unique laminar spiral inlet geometry designed to deliver sharper separation, maximum capacity and longer wear life.

The CVXT tile lined hydrocyclones are available in a large range of sizes to process any feed tonnage requirement, the company said. All components are designed for ease of maintenance and efficient operation, it added.

“This innovative design provides a natural flow path into the cyclone body, allowing the feed stream to blend smoothly with the rotating slurry inside the chamber,” Weir said. The result is greatly reduced turbulence through the whole cyclone, dramatically improving the separation efficiency of the hydrocyclone, according to the company. It is also offers a much longer wear life than conventional involute and tangential feed inlet designs, the company added.

The Cavex® CVXT hydrocyclone can be fitted with an extended barrel which, again, increases efficiency by increasing the residence time in the hydrocyclone. This is especially for use with ores carrying a high content of near-density materials. The hydrocyclone is also available with different overflow configuration options to suit operational needs.

To maintain separate efficiency at different operating yields and spigot sizes, a wide range of vortex finder sizes ranging from 0.4 to 0.5 are available. “These are designed to maintain a strong air-core at the different sizes. The spigot sizes range from normal to extra high capacity to accommodate low yield ores. These can also be manufactured in different material to prolong the hydrocyclone life and efficiency,” Weir said.
