On-line detection is a high-tech limestone detection technology emerging in recent years, its basic principle is based on PGNAA technology, using a neutron source to strike the nucleus of the material under test, the nucleus of the material captures the neutron and releases gamma rays of characteristic energy, by detecting the energy of gamma rays, the type of the element can be known, and the intensity of the gamma rays released by the element is calculated by detecting the content. Compared with the traditional sampling analysis, this means of analysis is fast and accurate, and the biggest advantage is that the whole material detection eliminates the problem of sampling representation. The detection instrument is straddled on the belt machine, and the whole material on the belt machine is detected.
Sampling testing and online testing applied to the mining process of different links, they play different roles. As a result, we need to combine the two organically, rather than simply replace. Sampling and testing is necessary for the control and planning of the mine area and each palm face, and is the premise of reasonable dosing, while the crushed material is analyzed by the analyzer to provide a basis for timely adjustment of the material in the unloading pit. The two methods compensate each other and are organically combined to provide accurate detection, production and control of the mine.
