Breakthrough hydrocyclone technology

Metso introduced the MHC^TM CB (curved bottom). This new hydrocyclone is designed for superior particle separation with increased unit capacity and coarser cut sizes while minimizing the fines bypass. Ben Klein, Product Group Manager of Hydrocyclones at Metso, says: “The design of the MHC^TM CB is based on the proven MHC^TM Hydrocyclone but upgraded with new innovative features. The new hydrocyclone offers higher unit capacity in the classification process compared to standard hydrocyclone technologies. The MHC^TM CB is also capable of producing coarser overflow products for a given hydrocyclone size, allowing for greater flexibility in classification and especially beneficial to new coarse particle flotation circuits. Finally, it provides enhanced classification efficiency by minimizing unwanted fines and water in the underflow.”

The MHC^TM CB hydrocyclone is ideal for grinding circuit classification – from primary to fine grinding – and for a full range of mineral types, such as lithium, gold, aggregates, nickel, magnetite, hematite, limestone, aluminum, zinc, molybdenum, silica, etc. It is highly compatible with dewatering and desliming applications. MHC^TM CB is a great product for greenfield and brownfield projects – and its simple design makes it easy to retrofit into existing hydrocyclone clusters.

“The MHC^TM CB was developed in partnership with Anglo American. Anglo American has provided support with both large-scale laboratory and pilot testing to prove the technology. Imperial College has also provided support in bringing this concept to light and in confirming the validity of this new technology as a third party,” Klein explains. Thanks to its energy efficiency and reduction in CO₂ emissions compared to similar wet classification technologies, the MHC^TM CB hydrocyclone has been approved as part of Metso’s Planet Positive offering.
