Metso Grande Series high-capacity screens: circuit design notes for plant engineers
Reviewed by Joe Ashwell
30 Second Briefing
Metso has launched its Grande Series™ of high-capacity stationary screens, introducing three new types – GLH, GMF and GFF – for demanding mining and aggregates applications. The range targets high-throughput, multi-deck screening duties where conventional units struggle with capacity, blinding or large feed size. For plant designers and process engineers, the new models expand options for fixed crushing and screening circuits needing greater tonnage and sharper separation without moving to multiple parallel screens.
Technical Brief
- Grande Series™ units are stationary screens, targeting fixed crushing and screening plant layouts.
- GLH, GMF and GFF models are differentiated by screening duty and motion type for process optimisation.
- Designs are described as “high-capacity”, aimed at single-machine duties rather than multiple parallel screens.
- Metso positions the series for both mining and construction aggregates circuits, covering hard rock and softer ores.
- Engineering focus is on productivity and efficiency, implying reduced recirculating loads and sharper size classification.
- Units are specified for “demanding” screening, indicating suitability for abrasive materials and high-impact feed conditions.
Our Take
Metso’s Grande Series launch comes alongside other recent process-equipment moves in our coverage, such as the circa-€55 million package for Harmony’s Eva copper project, signalling a push to lock in full flowsheet positions rather than just stand‑alone machines.
With both the Grande Series and the third‑generation OKTOP® Cooling Tower appearing in recent Metso items, the company is clearly targeting higher-capacity, more compact plant layouts, which will appeal to brownfield operators trying to debottleneck without major civils work.
Across the 407 tag‑matched ‘Projects’ and ‘Product’ pieces in our database, Metso appears frequently, suggesting that OEM selection for new screening lines like Grande Series is increasingly consolidating around a few large suppliers with integrated service offerings.
