Hydrocyclone Curved Bottom technology enhances efficiency and maximize capacity

Metso has introduced the newest member of its MHC hydrocyclones product family, 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, making it a true breakthrough technology for the classification process. Thanks to this unique patented design, the new hydrocyclone offers higher unit capacity 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. 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.

“In an effort to better support our partners and customers, the MHC^TM CB was developed in partnership with Anglo American, which has worked with Metso since the onset in investigating improvement in hydrocyclone classification. 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.

Metso is happy to promote this product for a variety of applications including, but not limited to lithium, gold, aggregates, nickel, magnetite, hematite, limestone, aluminum, zinc, molybdenum, silica, etc.

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.
