FLSmidth KREBS gMAX 26 Hydrocyclone

The FLSmidth KREBS gMAX 26 Hydrocyclone is a large-diameter classification cyclone designed for high-throughput primary classification duties in mineral processing circuits that handle coarse particles and high solids concentrations. With a 26-inch (660mm) barrel diameter, the gMAX26 is positioned for applications where throughput per unit must be maximised to minimise the number of cyclones in a cluster — reducing manifold complexity, civil footprint, and maintenance requirements in large-scale operations. The gMAX26 is particularly suited to primary classification of SAG or AG mill discharge at 150–400 micron cut points, and for thickener and CCD circuit feed preparation at medium-to-coarse cut points where large-diameter units handle the volumetric flow more efficiently than clusters of smaller cyclones.

The gMAX26 body is available in KREBS' proprietary wear-resistant materials system with multiple liner hardness and profile options. At Maaden Phosphate Company's Wa'ad Al-Shamal plant — the world's single largest phosphate mining and processing complex — the beneficiation circuit handles millions of tonnes of phosphate ore per year through milling and classification stages. The gMAX26 diameter allows each unit to handle 400+ m³/h of feed slurry, meaning a smaller cluster size achieves equivalent classification duty to a larger cluster of gMAX15 units. Fewer units means fewer pressure sensors, fewer apex and vortex finder change-outs, and simpler maintenance scheduling — all significant operational benefits at Wa'ad Al-Shamal's remote desert location where every maintenance activity requires careful advance planning.

The Saudi Vision 2030 mining expansion programme is driving significant investment in new mineral processing infrastructure. Ma'aden's Phase III phosphate expansion, Ma'aden's bauxite and alumina growth plan, and new PIF-backed strategic mineral investments all specify large-scale classification cyclones that can handle the throughput of modern high-capacity SAG-ball mill grinding circuits. The gMAX26 is sized correctly for these applications and is already proven in analogous phosphate and alumina operations internationally. FLSmidth's global reference database and application engineering support provide confidence in gMAX26 selection for Saudi greenfield projects.

Razz Middle East supplies FLSmidth KREBS gMAX26 hydrocyclones as both standalone replacement units for existing KREBS installations and as complete engineered cluster packages. Our in-kingdom engineering team provides cut-point modelling using FLSmidth's cyclone selection software, cluster design with feed distributor and launder layout, and full commissioning and operator training. Local spare part inventory for gMAX26 liners and wear components is maintained in Dammam for rapid response.
