1. High Processing Capacity: With a maximum handling capacity of up to 360 m³/h (depending on the model), GN’s triple shale shaker efficiently processes large mud volumes—critical for high-rate drilling operations common in the Middle East. The shakers feature adjustable vibration intensity and optimized screen angles, ensuring consistent separation even with heavy, high-solids mud. For detailed specifications on different models, check out GN’s Shale Shaker Product Line.

2. Superior Particle Separation: The integrated mud cleaner uses high-efficiency hydrocyclones to target fine particles (down to 20-40 microns) that escape the primary shakers. These hydrocyclones work in tandem with a secondary shaker deck, ensuring that nearly all usable mud is recovered. This level of purification reduces the need for fresh mud additives, lowering operational expenses significantly. GN’s hydrocyclones are part of a comprehensive solids control system; learn more about their design and performance on the Hydrocyclone Product Page.

3. Durability for Harsh Conditions: Middle Eastern drilling sites are known for extreme temperatures and dusty environments. GN’s equipment is built to withstand these challenges: the shaker frames are constructed from heavy-duty steel, and all electrical components are IP54-rated for dust and water resistance. The screens, a critical component of the system, are made from high-wear polyurethane or stainless steel mesh, ensuring long service life even with abrasive drill cuttings. To explore GN’s durable screen options, visit the Shaker Screens Page.

4. Easy Maintenance & Compliance: GN prioritizes user-friendly design. The triple shale shaker features quick-change screen systems, allowing operators to replace screens in minutes—minimizing downtime. Additionally, the system is designed to meet the Middle East’s strict environmental regulations, with enclosed mud tanks and spill-proof designs that prevent soil or water contamination.
