METHOD AND DEVICE OF AUTOMATIC NON-DESTRUCTIVE CONTROL OF MAGNETIC IRON CONTENT IN SLURRY FLOW

Journal Title: Computer Science Information Technology Automation - Year 2017, Vol 1, Issue 7

Abstract

The object is to investigate the automatic non-destructive control of iron ore slurry characteristics in ore concentration and to propose the method and the device of automatic non-destructive control of magnetic iron content in slurry flow. The methods of systematization and analysis of specifics of ultrasonic waves propagation, mathematical and computer modelling, computer technologies and experimental investigations provide the results. The scientific novelty consists in method of controlling the magnetic iron content in the slurry flow improving based on the Lamb waves propagation parameters assessment. The expression for determining the fraction of the ferromagnetic component in the slurry solid phase which contains the ratio of the measured Lamb waves amplitudes both in the magnetic field and without it and also contains the ratio of the Lamb waves amplitudes in the presence of the slurry and pure water in the measuring module (with no magnetic field was considered. The practical significance of the studies is a flow chart of the device based on the Lamb waves propagation for controlling the magnetic iron content in the slurry proposing. The results of the research investigate the regularities of the Lamb waves propagation in a metallic plate in contact with the iron ore slurry under various characteristics of the magnetic field was proposed. On the basis of the regularities of ultrasonic waves propagation in a metallic plate in the presence of the magnetic field, the authors analyze basic factors determining the magnetic susceptibility value, in particular, the size, form and initial magnetization of solid phase particles in the iron ore slurry. The method of controlling the magnetic iron content in the slurry flow is suggested based on the Lamb waves propagation parameters assessment.
