Metso Introduces Fine Classification Solutions

Metso introduced a new generation of fine classification technologies, the Metso MHC Series Hydrocyclone and the Metso UltraFine Screen. With this new offering, Metso is making it easier for customers to adopt next-generation, fine classification technologies to improve efficiency and profitability.

The MHC Series Hydrocyclone is designed specifically for grinding circuit classification duties. Developed in collaboration with Metso’s simulation and modeling scientists, the design focuses on optimized process performance, superior wear component design, and improved ease of maintenance.

These new hydrocyclones are ideal for classification duties ranging from primary grinding to fine regrinding applications across the full range of mineral types. The new product improves Metso’s existing equipment offering, which now covers the supply of entire grinding circuit systems.

In the area of wet fine screening classification, the Metso UltraFine Screen provides accurate and cost-effective separation technologies through reduced energy and water consumption. It directly classifies particles by size via the physical dimensions of the screening media aperture.

The improved separation efficiency and resulting reductions in material handling and comminution energy lead to substantial savings in overall operating costs. Screening performance is less influenced by plant operational variability and can positively impact downstream recovery processes.

Relative to other fine screen technologies, Metso’s UltraFine Screen doubles the screening area of a single machine, according to the company. This is achieved through its modular design consisting of up to 10 individual screen decks nested together into a single vibrating assembly along with a feed distribution system to ensure accurate and even feed distribution across the width of each screen deck.
