Designed specifically for grinding circuit classification duties, the new MHC Series Hydrocyclone was developed in collaboration with Metso's simulation and modelling scientists. The design focuses on optimised process performance, superior wear component design, and improved ease of maintenance.

These new hydrocyclones are for classification duties ranging from primary grinding to fine regrinding applications across the full range of mineral types. Metso's equipment offering now covers the supply of entire grinding circuit systems for mining customers.

The new UltraFine Screen provides accurate and cost-effective separation with reduced energy and water consumption. It directly classifies particles by size via the physical dimensions of the screening media aperture. Metso said the improved separation efficiency and resulting reductions in material handling and comminution energy lead to substantial savings in the overall operating costs. Additionally, screening performance is less influenced by plant operational variability and can positively impact downstream recovery processes.

The reduction in the overall capital expenditure needed and operating costs allows customers to quickly pay back the investment, leading to higher profitability.

Relative to other fine screen technologies, Metso said its UltraFine Screen doubles the screening area of a single machine. This is achieved through a modular design consisting of up to ten 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 individual screen deck. This reduces the space and infrastructure required for integration into the plant.
