Research Of Iron Content Rapid Measurement System For Magnetite Based On Self-Induction Effect

Iron grade is one of the important indicators for measuring the quality of iron powder. In recent years, with the rapidly increasing of the market demands and the continually scale expanding of the mineral production, the method of quick test has been gradually concerned by iron ore processing enterprises and steel business. The method that chemical analysis is usually used to test the iron grade of iron ore is accurate and reliable. But it is not able to meet the demands of mass and automation in modern beneficiation test. It requires some special conditions, such as specific reagents, particular test personnel, specific test procedures and specific environment. In order to realize the real-time and rapidity of grade test in the process of iron ore processing, manufacturing, and selling, the development of powered iron is becoming imminent.Based on the current situation of magnetite iron content measurement methods, this paper study of magnetite iron content measurement method based on the self-inductance inductor sensor, design a magnetite iron fast real-time measurement system. system including a collection information module inductive sensor as the core and a micro-processing module with PIC as the core. Since the sensor output signal is small and the permeability of the magnetite powder susceptible to temperature, humidity, and iron powder compaction rate, in this paper, through experimental analysis of iron powder compaction rate, temperature and humidity and other factors affecting the performance of the sensor output. Solutions for the regression model various parameters with respect to the output voltage. And text the regression model and the significance of the regression coefficients. And integrated computing iron content of magnetite. Inductance inductor sensor system have an advantage of real-time measurement, easy operation, compact, little affected by the environment, etc. Judging from the direction of development, research of rapid measurement magnetite iron content have meet the needs of the international steel industry’s development, and make our iron ore industry towards high efficiency, intelligent direction.
