NOUFERROUS METALLURGICAL EQUIPMENT

This article conducts process research and cause analysis on the damage of the impeller of the high-temperature preheater feeding pump in the high-pressure acid leaching system of a certain project's laterite nickel ore during the trial run and production process. The root cause of the problem is identified, providing a feasible basis for solving the problem, and optimizing and improving the existing operating procedures and trial run plan. The process design, equipment selection, structural design, material selection and other aspects play a qualitative role, providing guidance and reference cases for solving similar project problems.
