Hebei GN Solids Control Co., Ltd. has specialized in solids control and waste management equipment since 2008. GN stands as one of the largest manufacturers of solids control equipment globally. We operate three factories spanning a total area of 110,000 square meters in China and maintain branch offices with service capabilities in both the United States and Australia. Designated as a National High-Tech Enterprise, GN boasts a robust management system. Since 2010, we have consecutively held the American API Quality Management System Certification for 15 years and maintained China Classification Society certifications for ISO9001, ISO14001, and ISO45001 over many years. Our solids control equipment bears certifications from EU CE, ATEX, and International IECEx. GN employs an ERP Cloud + CRM Cloud management system for seamless production and operation, ensuring digital control over the production process and quality traceability. Approximately 70% of our products are exported internationally, reaching over 70 countries worldwide.
GN design and manufacture both decanter centrifuge and three-phase centrifuge for industry separation. Solid bowl decanter centrifuges have been operating according to the same basic principle since the 19th Century.
GN design specific centrifuges according to specific separation tasks and the use of resilient, high-quality materials have improved the performance of the centrifuges.
Moreover, GN owns a branch for design PLC and electrical control system; this gives GN advantages in electrical components for measuring and control technology. The performance and availability of the decanter centrifuge or three-phase centrifuges are significantly improved by the control system..
Main Application of GN Industry Centrifuges
- Dewatering sludges / mud and suspensions
- Thickening sludges or mud
- Clarifying different type liquids
- Separating 3-phase mixtures, i.e. two immiscible fluid phases and a solid phase
- Classifying solids in a wet suspension by grain size
- Separation of solids according to various densities
The GN Vertical Cutting Dryer uses centrifugal force to dry drilled solids in oil or synthetic base fluids. A stainless steel screen bowl traps “wet” solids and accelerates them up 900RPM with G force to 420G. Liquid is forced through the screen bowl openings, while “dry” solids are extracted by the angled flights attached to the cone, which rotate slightly slower than the bowl. Tungsten carbide protects the flights from abrasive solids and ensures long operational life. This aids in maintaining a constant gap between the scroll and screen bowl, which is crucial for proper operation.
