GN Delivers 7 Units Decanter Centrifuge for Chemical Salt Dewatering
GN Separation is pleased to announce the recent delivery of seven units of decanter centrifuges to a chemical processing customer specialized in chemical salt production. These centrifuges will be used for the continuous dewatering of a variety of inorganic chemical salts, a process that demands high-efficiency solid–liquid separation and consistent reliability. Chemical salt manufacturing typically involves crystallization, washing, and separation steps, and the performance of the dewatering equipment directly influences product purity, production efficiency, and overall plant stability. GN’s decanter centrifuge solutions have been engineered specifically to meet these demanding conditions.

Chemical salt dewatering places unique requirements on centrifuges due to the characteristics of the materials involved. Salts such as sodium chloride, potassium chloride, sodium sulfate, and ammonium salts often have high density, sharp crystal edges, and corrosive chemical properties. These factors require centrifuges that can withstand high abrasion, resist corrosion from chloride-rich brine, and maintain stable operation under high G-force. GN’s chemical decanter centrifuges are developed with duplex stainless steel or equivalent anti-corrosion materials for all key wetted components, while critical wear surfaces are protected with tungsten carbide to ensure long-term durability. This construction allows the equipment to run continuously with minimal maintenance, an essential requirement for chemical plants operating around the clock.

During the dewatering process, the centrifuge must efficiently separate a large volume of crystal slurry while maintaining low moisture content in the discharged solids. Achieving the right dryness level not only improves product quality but also significantly reduces the energy consumption of downstream drying systems. GN decanter centrifuges offer high rotational speed and optimized bowl design to generate strong centrifugal force, ensuring rapid separation of crystals from the mother liquor. The stable and controlled differential speed of the screw conveyor further enhances cake dryness and allows operators to fine-tune performance based on changes in feed concentration or crystal size. This ensures that the final salt product maintains consistent quality even under fluctuating production conditions. The improved separation efficiency also contributes to higher production throughput, allowing chemical plants to operate more efficiently and with reduced operational costs.
The functionality of the centrifuge is further enhanced when combined with GN’s advanced control system. For these seven delivered units, GN equipped the customer with intelligent control technology that allows real-time adjustment of bowl speed, differential speed, torque load, and feed rate. This level of automation is critical for chemical salt operations, where variations in slurry density, crystal load, or temperature can impact equipment efficiency. By continuously monitoring vibration, temperature, and operating parameters, the control system enhances operational safety and prevents potential failures, ensuring long-term stable operation.

The delivery of these seven decanter centrifuges demonstrates GN’s continued commitment to supporting the chemical industry with high-performance solid–liquid separation technologies. GN has accumulated extensive experience in the fields of oil and gas, mining, industrial wastewater, and environmental engineering, and this project further strengthens the company’s presence in chemical salt processing. With increasing demand for high-purity salt and greater emphasis on production efficiency and reliability, GN will continue to expand its technical capabilities and supply advanced centrifuge solutions tailored to the needs of global chemical manufacturers.
GN Solids Control looks forward to supporting more customers with efficient, reliable, and durable decanter centrifuge systems for chemical salt dewatering and other industrial separation applications.
