The Study Of γ-ray Coal Ash Content Apparatus Application To The Jigging Coal Running

Coal is the main energy of our country, how to make use of the coal and raise exploitation efficiency is very important to the national economy . Among them, the exaltation of the jigging coal running technique level is the most important , the study of Y -ray coal ash content apparatus application on jigs belongs to this field.On the basis of study of layering theories on jigs, the online measure about the fine coal by Y -ray coal ash content apparatus , the repetition control of the fine coal automatically , the online measurement principle and demarcate of Y -ray coal ash content apparatus , this paper has concluded that the particle size and containing water quantity of the fine coal are the two main factors to the accuracy of the ash measuration, by analysing the local data of Baishan factory, then we do the contrast experiment to the fine coal product of two kinds of craft at the laboratory, for the sake of reducing the influence of both factors, ulteriorly, we make the design project of the improving efficiency.At last, we build up the related mathematics model. By the application of the model, we can make the ash of the fine coal product near to the true value further, thus the fine coal product has the higher credibility.
