Improving Mining Slurry Management with GN Large Bowl Decanter Centrifuge Technology
Mining operations generate large volumes of slurry during mineral processing, tailings management, and water recovery processes. Efficient solid-liquid separation plays an important role in improving process efficiency, recovering valuable water resources, and supporting more sustainable mining practices.
For a domestic mining slurry concentration application, GN Separation supplied a GN 30-inch bowl diameter decanter centrifuge, designed to provide continuous separation performance for large-scale slurry treatment requirements.

Efficient Solid-Liquid Separation Solution for Challenging Oil Sludge Applications
Tank bottom sludge management has always been a major challenge for oil storage terminals and refineries. Due to long-term storage, crude oil tanks gradually accumulate a complex mixture of heavy hydrocarbons, water, sand, corrosion products, and fine solids at the bottom of the tank. This sludge is difficult to handle, requires significant manpower, and often creates high disposal costs.
To address these challenges, GN Separation supplied a GNLW554-VFD Large Bowl Decanter Centrifuge for an oil sludge treatment project in Africa, providing an efficient solution for continuous solid-liquid separation and sludge volume reduction.

Hebei, China – July 1, 2026 – GN Smart Control Technology Co., Ltd. (official website: https://www.gnsmartcontrol.com) has officially launched its full-spectrum product portfolio, encompassing explosion-proof electric control cabinets, standard industrial control cabinets, and fully integrated intelligent control system solutions. The company delivers custom-engineered automation control products that meet international certification standards, serving global clients across the oil & gas, mining, tunnel engineering, wastewater treatment, infrastructure construction and other key industrial sectors.

Built upon the robust industrial foundation of GN Separation, the company inherits decades of rich on-site project experience in solid-liquid separation machinery. Its core technical team has long provided dedicated support for GN Separation’s projects deployed in more than 70 countries and regions worldwide, with specialized expertise in the R&D, manufacturing and delivery of electric control systems, industrial automation platforms, and complete intelligent slurry pump control units. All control products are designed for full seamless compatibility with GN Separation equipment, enabling the company to deliver integrated turnkey industrial solutions to end users across the globe.

The company’s offerings are structured into three core product categories: the explosion-proof electric control series, general-purpose industrial control cabinets, and integrated intelligent control systems. The explosion-proof cabinet line holds a complete set of authoritative global explosion-proof certifications including CNEX, ATEX and IECEx, covering explosion-proof PLC control cabinets, frequency conversion cabinets, soft starter boxes, explosion-proof junction boxes and more. These products fully satisfy the strictest safety requirements for flammable and explosive working conditions such as oil & gas drilling, underground mining and petrochemical operations. For general industrial scenarios, the standardized PLC control cabinets, motor starter cabinets and power distribution boxes ensure the stable automated operation of wastewater treatment facilities and tunnel construction machinery.

Beyond individual cabinet units, GN Smart Control also provides turnkey intelligent packaged systems, including PLC automation systems, SCADA remote monitoring platforms, centralized power distribution units and integrated motor control systems, to realize full-process digital monitoring of production lines.
Supported by the group’s 80,000-square-meter modern intelligent manufacturing park, the company implements rigorous full-process quality inspection protocols and maintains highly flexible, fast-delivery capabilities. Its global service network is fully interconnected with GN Separation’s worldwide layout, with self-operated subsidiaries equipped with local warehouses and after-sales teams established in the United States, Australia and the UAE in the Middle East, alongside authorized service partners in more than 10 countries and regions. This structure ensures that overseas customers can access timely localized technical support as well as on-site equipment installation and commissioning services.
What sets GN Smart Control apart from ordinary electrical control manufacturers is its one-stop customized service capability. Its engineering team develops tailor-made control solutions based on each client’s specific project parameters, covering the entire value chain from conceptual design, production and manufacturing to on-site commissioning and long-term after-sales maintenance. By integrating the two major business segments of separation equipment manufacturing and intelligent control R&D, the company fills a long-standing market gap for dedicated supporting control systems for global industrial solid-liquid separation production lines.

A senior executive at GN Smart Control commented: “The original intention of establishing GN Smart Control was to complete the supporting industrial chain for GN Separation. We deeply integrate mature separation equipment technology, safety-compliant electrical control products and intelligent remote monitoring systems, to help global customers improve equipment operation safety, reduce energy consumption and enhance overall project operational efficiency. Looking ahead, we will continue to upgrade our explosion-proof and intelligent control product lines, to deliver more reliable and cost-effective automation solutions for diverse industrial separation working conditions.”
Moving forward, GN Smart Control will increase R&D investment in digitalized and cloud-connected control systems, to further achieve full compatibility between its control products and GN’s full range of equipment, including vibrating screens, decanter centrifuges and sludge treatment systems. The company will also continue to expand its global business footprint to serve more industrial customers worldwide.

Efficient Water Recycling Solution for Domestic Food Processing Plants
In modern food processing plants, especially potato chip and pre-cut potato slice production lines, large volumes of flushing water are generated during washing and cutting processes. This wastewater typically contains a significant amount of free starch, fine fibers, and suspended solids.
Instead of discharging this valuable stream as waste, a decanter centrifuge can be used to efficiently recover starch and enable water recycling, significantly reducing operating cost and environmental load.
