GN Separation is delighted to announce the triumphant dispatch of four packages of Mini Decanter Centrifuges to a European client. These centrifuges are set to be used for solids-liquid separation in the treatment of mud from mineral exploration. The entire process, from manufacturing and assembly to testing and shipping, adhered strictly to the project schedule, marking yet another significant achievement for GN in delivering compact and highly efficient separation solutions to the global market.

GN’s Mini Decanter Centrifuge is meticulously crafted for small-capacity and pilot-scale scenarios, while still retaining the fundamental benefits of full-sized decanter centrifuges. Leveraging high-speed centrifugal force, this equipment can continuously separate fine solids from drilling mud. This process reduces the solids content in the liquid phase, facilitating the reuse or further treatment of the clarified fluid. Additionally, the separated solids become easier to manage, transport, or dispose of, thereby substantially enhancing overall site efficiency.

For this particular project, the four centrifuge units were provided as compact, modular packages. This design ensures effortless transportation, straightforward installation, and seamless integration into the customer’s existing process flow. The skid-mounted configuration minimizes the need for on-site civil work, making the system ideal for temporary or mobile exploration sites. Despite their compact size, these units are engineered to provide stable performance, exhibit low vibration levels, and operate reliably under continuous duty conditions.

One of the standout features of GN’s mini decanter centrifuges is their operational versatility. The adjustable bowl speed and differential speed enable the equipment to adapt to variations in slurry density, particle size distribution, and flow rate—challenges commonly encountered in the treatment of exploration drilling mud. The robust mechanical design, coupled with the use of wear-resistant materials for critical components, guarantees a long service life and reduces the need for frequent maintenance.

Throughout the project's execution, GN’s technical and project teams collaborated closely with the customer to gain a comprehensive understanding of the application requirements and operating conditions. Based on this insight, the equipment configuration was fine-tuned to ensure reliable separation performance while maintaining energy efficiency. Prior to shipment, all units underwent rigorous inspection and test runs to verify their mechanical integrity and operational stability.

The successful delivery of these four mini decanter centrifuges to Europe further underscores GN Solids Control’s expertise in providing customized solids control and separation solutions across a diverse range of industries, including mining, exploration drilling, environmental protection, and industrial wastewater treatment. As the global demand for compact, efficient, and environmentally friendly separation technologies continues to rise, GN remains dedicated to ongoing innovation and customer-centric engineering.

GN Separation is committed to continuing its support for customers worldwide by offering reliable equipment, professional technical assistance, and time-tested solutions for solids-liquid separation challenges, whether in large-scale operations or specialized applications.

Ports handling iron ore face constant challenges: large throughput, abrasive materials, high moisture content, and the need for stable, continuous operation.
