A new industrial application of magnetic separation
A new industrial application of magnetic separation
The aim of this work was to investigate the application of magnetic separation to the removal and recovery of carbon steel grinding swarf from machining fluids used in large-scale industrial manufacturing processes such as in the automotive industry. Magnetic separation is a technology which has found widespread application in the mineral processing industry and in particular the beneficiation of kaolin clay for use in the paper industry.
The technical feasibility of the application was demonstrated in the early stages of the work by the successful treatment of industrial samples using a crude laboratory-scale separator. In addition, the fluid and swarf material underwent extensive analysis using electron microscope-based optical and spectroscopic techniques in order to ascertain the presence of other undesirable components of the fluid that would require removal also. It was demonstrated by these results that the overall objective of the project was the development and testing of a laboratory-scale system which would allow the optimum operational parameters to be ascertained for the design of a commercially viable, large scale system.
A series of detailed trials on large volumes of industrial samples was carried out in conjunction with the development of the modifications that were required to existing magnetic separation theory in order to accommodate the particulars of this application. The trial system was tested to low applied magnetic strengths and high fluid flow velocities in order to optimise the economies of the application, resulting in extraction efficiencies of the order of 99.998% being achieved. During the course of the project, a new type of matrix cleaning system was developed for which a patent was applied and this was successfully tested in the trial system. Economic appraisal of the application suggests that an industrial-scale system could provide reliable, high quality recovery of grinding swarf at a cost of around one cent per cubic metre of fluid. Overall, the results from the project have provided the foundation for the application of magnetic separation to this application.

Abstract
The aim of this work was to investigate the application of magnetic separation to the removal and recovery of carbon steel grinding swarf from machining fluids used in large-scale industrial manufacturing processes such as in the automotive industry. Magnetic separation is a technology which has found widespread application in the mineral processing industry and in particular the beneficiation of kaolin clay for use in the paper industry.
The technical feasibility of the application was demonstrated in the early stages of the work by the successful treatment of industrial samples using a crude laboratory-scale separator. In addition, the fluid and swarf material underwent extensive analysis using electron microscope-based optical and spectroscopic techniques in order to ascertain the presence of other undesirable components of the fluid that would require removal also. It was demonstrated by these results that the overall objective of the project was the development and testing of a laboratory-scale system which would allow the optimum operational parameters to be ascertained for the design of a commercially viable, large scale system.
A series of detailed trials on large volumes of industrial samples was carried out in conjunction with the development of the modifications that were required to existing magnetic separation theory in order to accommodate the particulars of this application. The trial system was tested to low applied magnetic strengths and high fluid flow velocities in order to optimise the economies of the application, resulting in extraction efficiencies of the order of 99.998% being achieved. During the course of the project, a new type of matrix cleaning system was developed for which a patent was applied and this was successfully tested in the trial system. Economic appraisal of the application suggests that an industrial-scale system could provide reliable, high quality recovery of grinding swarf at a cost of around one cent per cubic metre of fluid. Overall, the results from the project have provided the foundation for the application of magnetic separation to this application.
