GN Separation is pleased to announce the successful delivery of seven decanter centrifuges to a chemical processing customer specializing in chemical salt production. These units will be deployed for the continuous dewatering of various inorganic chemical salts—an application that requires high-efficiency solid–liquid separation, operational reliability, and long-term mechanical durability. Chemical salt production typically involves crystallization, washing, and centrifugation stages; therefore, the performance of the dewatering equipment has a direct impact on product purity, production stability, and overall plant efficiency. GN Separation’s decanter centrifuge solutions are engineered specifically to meet these demanding industrial conditions. 
Chemical salt dewatering places unique requirements on decanter centrifuges due to the properties of the materials involved. Salts such as sodium chloride, potassium chloride, sodium sulfate, and ammonium-based crystals generally feature high density, sharp particle edges, and corrosive chemical characteristics. These traits necessitate equipment capable of withstanding abrasion, resisting corrosion from chloride-rich brines, and maintaining stable operation under high G-force.
GN Separation’s chemical decanter centrifuges are constructed using duplex stainless steel or equivalent anti-corrosion alloys for all key wetted components. Critical wear surfaces are protected with tungsten carbide, significantly extending service life under harsh conditions. This robust construction allows reliable, continuous operation with minimal maintenance—an essential requirement for chemical plants running 24/7.
During dewatering, the decanter centrifuge must efficiently handle large volumes of crystal slurry while ensuring low residual moisture in the discharged solids. Achieving optimal dryness improves final product quality and reduces the energy load on downstream drying equipment.
GN Separation’s decanter centrifuges feature high rotational speeds and an optimized bowl design to generate strong centrifugal forces, enabling rapid and thorough separation of crystals from the mother liquor. The stable and precisely controlled differential speed of the screw conveyor ensures consistent cake dryness and allows operators to adjust performance based on variations in feed concentration, crystal size, or slurry characteristics. This capability ensures product consistency even under fluctuating production conditions and significantly enhances throughput, ultimately reducing operational costs.
The performance of the centrifuge is further elevated through GN’s advanced intelligent control system. For these seven units, GN Separation provided automated controls capable of real-time adjustment of bowl speed, differential speed, torque, and feed rate. Such automation is crucial in chemical salt processing, where changes in slurry density, crystal loading, or temperature can affect separation efficiency. The system continuously monitors vibration, temperature, and other operating parameters, improving operational safety, preventing equipment failures, and ensuring long-term stable operation.
The delivery of these seven decanter centrifuges demonstrates GN Separation’s ongoing commitment to supporting the chemical industry with high-performance solid–liquid separation technologies. With extensive experience in oil and gas, mining, industrial wastewater, and environmental engineering, GN Separation continues to strengthen its presence in the chemical salt sector. As global demand for high-purity salts grows and manufacturers seek greater efficiency and reliability, GN Separation will continue developing advanced, application-specific decanter centrifuge solutions tailored to the needs of chemical producers worldwide.
GN Separation looks forward to supporting more customers with efficient, reliable, and durable decanter centrifuge systems for chemical salt dewatering and a wide range of industrial separation applications.
