| titleOfInvention | Method for automatic quality control of coal on conveyor belt |
| abstract | The invention relates to mining automation, and more specifically to methods and devices for automatic quality control of coal on a conveyor belt, and can be used in coal preparation plants, coking plants, mines, thermal power plants, coal cuts. The aim of the invention is to reduce the control error while reducing the cost. In the method of automatic quality control of coal on a conveyor belt, which includes irradiating a coal flow with electromagnetic radiation, registering electromagnetic radiation scattered by coal, measuring its intensity and determining the measured ash content, humidity, coal density and sulfur content in it, the coal is irradiated from above the flow in the middle of the cargo branch of the conveyor belt with a collimated gamma-ray beam in the energy range of not less than 50–310 keV and record the intensities of li, Ig, and h in the back scatter carbon gamma radiation in the energy ranges, respectively, 50-70. 150-175 and 230-310 keV, in the field of inversion. the dependence of the intensity of scattered gamma radiation with an energy of about 230 keV on density. And for a few. For example, for five, values for ash, moisture, density, and sulfur content, uniformly filling the whole range of their measurements, each of the three intensities is measured several times and their average values are determined, after which the next two are determined. intensities to the corresponding average values of intensity and, accordingly, judge about ash content, humidity, coal density and sulfur content in it. 4 il.
