Hydrocyclones have been integral to the mineral processing industry for many years, continuously evolving alongside other technological advancements. Many mining concentrator plants have targeted increased mill circuit throughputs, whereby most hydrocyclones installed in the clusters are operated without standby capacity and with limited space to cater for expanded installation footprints. This paper aims to explain advancements in CAVEX® hydrocyclone technology, highlighting maximising recovery and capacity. Tests were conducted on a customer site using a 400CVXT10 and 400CVDT10 to evaluate comparative efficiency and volumetric flow capacity. All tests were conducted at the same feed process parameters. The results demonstrated an improvement in hydraulic capacity of up to 30% and separation sharpness by >10%. The 400CVDT10 results have been discussed in this paper and compared with the 400CVXT10 in a coal classification application. The main objective of this paper is to investigate the benefits of new CVDT hydrocyclone innovations and their impact on the coal industry.
