Abstract:
Purpose. To develop a method for complex ultrasonic measurement of such parameters of the iron ore slurry flow passing through the working chamber of the magnetic separator as efficiency, concentration and grade size distribution of solid-phase particles.
Methodology. The research uses methods of modelling processes of ultrasonic wave propagation in the iron ore slurry. Ultrasonic wave absorption and scattering in water with solid particles and air bubbles are considered. To characterize absorption and scattering of acoustic oscillations by oscillating gas bubbles, concepts of effective cross-sections of attenuation, absorption and scattering are introduced.
Findings. The dependence of the phase velocity of asymmetric Lamb waves on the wall thickness of the magnetic separator was obtained. As a result of computer simulation of the process of ultrasonic waves propagation, its time and frequency characteristics were obtained. Based on the data obtained using ultrasonic measurements, the coefficients of the Rozin-Rammler equation for the characteristics of the ore material at various points of the technological line were calculated.
Originality. The proposed method of ultrasonic measurement of characteristics of the iron ore slurry in the working chamber of the magnetic separator differs from the existing ones in the fact that the Lamb wave source operates in a wide pattern and is connected by a V-shaped scheme which makes it possible to create a beam of coherent waves propagating both in the container wall (the working separator chamber) and in the measured medium (the iron ore slurry).
Practical value. The practical value consists in developing an ultrasonic measuring channel scheme for determining characteristics of the iron ore slurry in the working chamber of the magnetic separator.
