Weir Minerals Africa recently manufactured a 20-way cluster of Cavex\u00ae 500 CVX hydrocyclones. This hydrocyclone delivers exceptional operational efficiencies, reduced wear and consistent metallurgical performance. With a design built for longevity, this unit is anticipated to exceed a 20 year lifespan because of its easily replaceable wear parts that ensure peak performance throughout its service life.<\/p>\n\n\n\n

The hydrocyclone cluster was specifically tailored to the classification and processing requirements of a gold project in West Africa. Lerato Ramanala, Product Manager Hydrocyclones at Weir Minerals Africa, says it will be used in a milling application as part of a flowsheet with an HPGR and ball mill \u2013 the Cavex\u00ae hydrocyclones will classify the mill discharge. Operating at a relatively low pressure of 73 kPa, the hydrocyclones are meticulously engineered to minimise equipment wear under demanding conditions.<\/p>\n\n\n\n

\u201cOur design process considered factors such as port sizes and pipe schedules, ensuring obstruction-free operation, even under challenging conditions in which the hydrocyclones have to contend with a wide range of particle sizes. The feed and discharge pipes were engineered to accommodate the required flow rate and pressure, maintaining a launder geometry that ensures optimal slurry levels during regular operation, without any spillage during normal and design operation,\u201d she explains.<\/p>\n\n\n

The hydrocyclone cluster operates efficiently: the overflow goes to the trash screen, the underflow launder diverts the discharge, returning some to the ball mill for further grinding, while the other portion is fed to a gravity circuit.<\/p>\n\n\n\n

Ramanala says the hydrocyclone cluster is custom-engineered featuring Cavex\u00ae hydrocyclones, Linatex\u00ae rubber linings and Isogate\u00ae WR valves. The Cavex\u00ae hydrocyclone features an innovative 360\u2070 laminar spiral inlet that significantly enhances separation performance.<\/p>\n\n\n\n

\u201cTo prolong wear life and reduce the need for frequent replacements, we’ve used R55 rubber, a patented Weir Minerals material, in the hydrocyclones\u2019 rubber inserts,\u201d she adds.<\/p>\n\n\n\n

To address abrasion resistance, Linatex\u00ae premium rubber, known to consistently outperform other rubber materials in abrasive wet processing applications, was selected. The integration of Linatex\u00ae rubber minimises maintenance requirements and guarantees optimal equipment performance.<\/p>\n\n\n\n

The Isogate\u00ae WR valve is a lightweight valve designed for a hydrocyclone cluster of this size, featuring advanced rubber sleeve technology for improved wear life and full bore design for unrestricted flow.<\/p>\n\n\n\n

\u201cNotably, this is the first greenfield cluster to incorporate Synertrex IIoT technology for performance monitoring, specifically to detect any roping or splashing events,\u201d Ramanala says. This proactive performance monitoring platform enhances the overall effectiveness of the Cavex\u00ae hydrocyclones by providing accurate data on cyclone performance, supporting the operator in maintaining optimal operating conditions, and enabling proactive intervention for unforeseen incidents.<\/p>\n\n\n\n

\u201cSynertrex is much more than a condition monitoring system for individual pieces of equipment. As the technology continues to develop and Weir Minerals works to leverage the equipment and process data it alone has as the OEM, its customers are increasingly seeing it as the preferred partner for intelligent solutions and digitally-enabled services,\u201d she says.<\/p>\n\n\n\n

Hydrocyclones provide cost efficient separation in mineral processing applications, especially compared to traditional screens. Even with its substantial size, a cluster of this magnitude maintains a more compact overall footprint, facilitating space optimisation within the process plant while still achieving the necessary cut point.<\/p>\n\n\n\n

Weir Minerals Africa’s experienced local team carefully analysed operational requirements, flow rates and pressure differentials when designing this Cavex\u00ae hydrocyclone cluster to maximise efficiency and meet required throughput rates. Structural integrity was a primary focus due to the cluster’s large size, and extensive use was made of computer-aided design (CAD) to ensure a robust design capable of withstanding demanding conditions. The structural design includes walkways, support beams and bracing mechanisms. The large cluster was manufactured at Weir Minerals Africa’s facility, undergoing trial assembly and quality checks before being disassembled and packaged for shipment to the customer. Installation on-site will be part of the greenfields process plant construction project, with Weir Minerals Africa specialists readily available for installation and commissioning support.<\/p>\n","protected":false},"excerpt":{"rendered":"
