Study on the relationship between magnetic uniform field range and key mechanical size in electromagnetic separation

Currently, the production of stable isotopes in high abundance primarily relies on electromagnetic separation methods. This approach necessitates the design of a uniform magnetic field of high quality. The extent of this uniform field depends on the particle deflection radius and divergence angle. Although determining this area is straightforward, ensuring its uniformity during the design of electromagnetic separation equipment poses significant challenges. Designing the mechanical dimensions of the pole shoe often requires extensive software simulations, theoretical calculations, and even experimental validations. This process can be complex and demanding. Poor selection and assessment during the design phase may result in failure to meet performance metrics or cause substantial increases in construction costs. This paper discusses the use of extensive software simulation data to analyze and summarize the relationship between the uniform field extent in the analysis magnet and the critical mechanical dimensions of the pole shoe. Verification through two existing electromagnetic separation devices will support the credibility of the findings, thus establishing a foundation for future projects that focus on the mechanical size design of uniform magnetic fields and offering theoretical guidance. This approach significantly alleviates design difficulties.
