摘要
介绍了 γ射线灰分仪测量重介产品灰分的模拟试验 ,研究了精煤表面粘附的磁铁粉量对γ射线灰分仪测量精度的影响情况。论述了灰分仪探测器及采样器的合理安装位置及工业性测定试验结果。
Introduced is the simulation experiment on ash measurement by γ ray sensor for coal products from HM process. Investigated is the influence of magnetite adsorption on clean coal surface on preciseness of ash value measured. Discussed are the proper installation of sensor probe and sampler of the apparatus and the industrial measurement results.
