Crude nickel sulfate raw materials contain various metallic impurities such as iron, copper, and zinc, as well as free acids. To achieve efficient purification, extraction is currently the most ideal process route. This technology, through a series of processes including nickel soap preparation, multi-stage extraction for impurity removal, and stripping regeneration, can deeply remove various impurity ions to obtain high-purity nickel sulfate products.

Addressing the challenges of long and complex processes in nickel sulfate extraction equipment selection, Zhengzhou Tiei Extraction's CWL-M series centrifugal extractors demonstrate significant advantages. In a recent successful customer project, the entire production line utilizes the CWL650-M centrifugal extractors, configured with 30 stages in series, achieving a total system processing capacity of 50-60 m³/h and over 8000 hours of stable operation annually, fully meeting the demands of large-scale production.

The CWL-M centrifugal extractor uses composite materials, has a drum diameter of 650mm, and a maximum speed of 580r/min. Combined with premixing and multi-stage mixing technology, it achieves efficient mass transfer and rapid phase separation. The equipment has a wide applicable flow ratio range (1/30 to 30/1), and can adapt to various material systems with viscosities ≤3000cps and specific gravity differences of 0.03 to 3. It is equipped with an explosion-proof motor and an electrostatic discharge device to ensure safe and reliable operation.

The CWL-M series centrifugal extractor performs excellently in all stages of nickel sulfate extraction and impurity removal. It not only effectively solves problems such as entrainment and emulsification in traditional processes, but also significantly reduces organic phase residue and operating energy consumption.
