Abstract

Способ определения магнитной восприимчивости железорудного материала на конвейере, включающий измерение сигналов двух индукционных зондов, размещенных под конвейерной лентой, отличающийся тем, что, с целью повышения точности, предварительно в процессе измерения сигналов индукционных зондов изменяют высоту слоя железорудного материала с фиксированным значением магнитной восприимчивости и снимают зависимость отношения предельного значения сигнала одного из индукционных зондов при определении магнитной восприимчивости исследуемого железорудного материала, в процессе измерения сигналов индукционных зондов определяют отношение сигналов индукционных зондов и по полученной зависимости определяют текущее значение отношения предельного значения сигнала индукционного зонда к значению сигнала этого зонда, а магнитную восприимчивость исследуемого железорудного материала определяют по предельному значению сигнала, которое находят из соотношениягде I- предельное значение сигнала;I- текущее значение сигнала индукционного зонда к значению сигнала этого зонда;I- текущее значение сигнала индукционного зонда.The method for determining the magnetic susceptibility of iron ore material on a conveyor, including measuring signals from two induction probes placed under the conveyor belt, characterized in that, in order to improve the accuracy of signals from induction probes, the height of the iron ore material layer with a fixed value of magnetic susceptibility is measured and removed the dependence of the ratio of the limiting value of the signal of one of the induction probes in determining the magnetic susceptibility is investigated about the iron ore material, in the process of measuring the signals of the induction probes, determine the ratio of the signals of the induction probes and determine the current value of the ratio of the limit value of the signal of the induction probe to the signal value of this probe, and the magnetic susceptibility of the studied iron ore material is determined by the limit value of the signal that is found from the ratio I is the limiting value of the signal; I is the current value of the signal of the induction probe to the signal value of this probe; I is the current e value induction probe signal.
