admin The launch, announced on April 10, adds another layer to Metso’s screening portfolio at a time when producers are under pressure to cut water use, reduce energy consumption and keep output consistent even as ore bodies, feed blends and recycled inputs become harder to handle. The company says the new units are intended for difficult and often moist materials, a part of the process where conventional screens can suffer from blinding, pegging and unstable separation.
Metso is positioning the GFF Series around two immediate use cases. One is fine aggregate production, including sand manufacturing, where screen performance has a direct bearing on particle consistency and saleable product quality. The other is mining circuits built around high-pressure grinding rolls, or HPGRs, where more accurate classification can ease downstream grinding loads and lift overall efficiency. That link to comminution is central to the company’s pitch, because screening is no longer treated simply as an ancillary step; in many plants it is becoming a key lever in energy management and throughput control.
According to the product details released with the launch, the GFF Series combines hybrid flip-flow and conventional deck technology with high excitation forces. Metso says that allows cut sizes down to 0.5 mm in dry applications and 0.3 mm in wet ones, while helping reduce clogging that can interrupt production. In practical terms, that matters because finer, more stable separation can mean fewer stoppages, better recovery of target sizes and less wasteful recirculation through grinding equipment.
Michael Gyberg, Metso’s vice president for screening equipment solutions, said customers had been seeking a screen capable of handling fine and moisture-prone material “without forcing them into wet screening”. That statement goes to the heart of a broader industry tension. Water remains a strategic constraint across many mining and quarrying jurisdictions, and equipment suppliers are increasingly framing new machinery around not only output gains but also resource intensity. Metso’s own corporate messaging has emphasised energy and water efficiency across its aggregates, minerals processing and metals refining businesses.
The technology itself is not new to industry. Flip-flow screens have long been used where sticky, fine or damp material defeats rigid screening surfaces. Academic and technical literature has repeatedly pointed to their advantages in handling fine-grained or viscous feed, chiefly because the elastic motion of the deck helps prevent aperture blocking and improves separation of hard-to-screen fractions. What Metso appears to be doing is bringing that principle more aggressively into mainstream aggregates and HPGR-linked applications, where customers are looking for a tighter fit between classification, energy use and overall circuit design.
That also aligns with the company’s wider commercial direction. Metso reported sales of about €5.3 billion in 2025 and had close to 18,000 employees across around 50 countries at the end of the year, underscoring the scale at which it can commercialise incremental equipment advances across global mining and aggregates markets. Earlier moves to expand its screening portfolio, including the Grande Series announced in December 2025, suggest the GFF launch is part of a deliberate effort to deepen coverage across different materials, plant layouts and throughput requirements.
Stefan Sakendorf, director for Metso’s HRC products, said finer cuts achieved with flip-flow technology could be a “major advantage” for future HPGR circuits. That matters because operators have been trying to extract more work from HPGR-based flowsheets, which are generally seen as more energy-efficient than some traditional grinding routes when properly configured. If the screening stage becomes more precise, a larger share of the workload can stay in the most efficient part of the circuit rather than spilling into energy-hungrier downstream stages.
