Keep your grinding circuits efficient and balanced

SAG mill discharge screening typically benefits from horizontal BRX Series configurations that maximise deck area and handle high tonnages with impact resistance. Horizontal orientation removes correctly sized material early, cutting recirculating load back to the mill and reducing specific energy consumption. The key is matching screen size, media, and motion profile to your mill throughput and target cut size. FLS screening process experts work with you to model the circuit, validate the configuration through motion analysis, and tune operating parameters to your ore characteristics. Site trials de-risk the approach before full implementation, ensuring the screen integrates seamlessly with mill discharge, pump capacity, and cyclone feed requirements. 

If you're experiencing pump blockages, cyclone plugging, or downstream equipment damage from tramp material - wood, bolts, liner fragments, rags - a UHS safety screen positioned at critical points (sump outlets, tank discharges, pump feeds) prevents these issues from becoming stoppages. Warning signs include frequent unplanned maintenance to clear blockages, pump trips, or visible tramp material in your process streams. FLS screening experts will audit your circuit to identify where protection screening would deliver the greatest impact on availability, then specify and size UHS units to match your flow rates and space constraints - often as retrofit installations with minimal disruption. 

If you're seeing carbon carryover into tailings or product streams in your gold circuit, a UHS carbon safety screen protects recovery and prevents downstream issues. FLS screening specialists can audit the circuit to identify where a safety screen will deliver the greatest benefit, specifying and sizing the UHS unit to your flow rates and available footprint - often as a retrofit with minimal disruption. 

Yes - and the impact can be significant. VSW dewatering screens remove water at the source, immediately after classification or beneficiation, returning process water to the circuit before it reaches thickeners and filters. This early water recovery reduces thickener overflow rates and eases filter duty, improving water balance across the plant and enabling cleaner, more conveyable product. The key is proper VSW sizing and media selection for your slurry characteristics - particle size distribution, solids content, and target moisture all influence performance. FLS screening specialists model the dewatering duty, recommend the appropriate VSW configuration, and validate performance through site trials to ensure you achieve the moisture targets and water recovery rates that justify the investment. 

FLS de-risks screen upgrades through a staged approach. An audit of existing screens with motion analysis benchmarks current performance and identifies issues (stroke, frequency, media wear, structural problems). Based on the audit results, our screening specialists will first recommend quick-win actions for your existing screens. If pursuing new screens, we validate the approach through site trials, confirming cut-size accuracy, capacity, and integration with cyclones and downstream equipment before rolling out across the circuit. Our metallurgical experts also model the circuit impact to ensure changes don't create bottlenecks or compromise grind quality. Installation is planned during scheduled shutdowns, with exchange bodies and commissioning support to compress downtime.  

FLS screens deliver sustainability benefits throughout the comminution circuit. Energy efficiency gains are significant: accurate classification at SAG discharge and in mill circuits reduces over-grinding and lowers specific energy consumption per tonne - often the largest energy user in mining operations. By removing correctly sized material early, screens help mills work only on particles that need grinding, cutting unnecessary kWh consumption. Water stewardship improves through VSW dewatering screens that recover process water at the source, returning it to the circuit sooner and reducing demand on energy-intensive thickeners and filters. Extended component life through vibration isolation, optimised motion profiles, and precision-engineered spares reduces material consumption and waste over the asset lifecycle. Safety improves through UHS trash and safety screens that remove hazardous tramp material before it causes equipment damage or personnel risk, while access-friendly maintenance designs minimize human-machine interactions. On the process side, FLS specialists support operations with expert circuit design and operating envelopes optimised for lower water and energy intensity, with lifecycle support to maintain performance as conditions change.
