一、概述煤炭灰分是煤炭质量最重要的一项指标,对煤炭分级、销售计价起着决定性作用。在选煤过程中,灰分对指导选煤生产、稳定精煤质量、提高洗选产率都起着关键作用。所以快速、精确地测定煤炭灰分是十分重要的。低能γ射线测灰仅用于煤炭生产,尤其是选煤过程中的在线或傍线测量精煤灰分,对指导选煤生产,稳定煤炭质量,提高精煤产率及选煤自动化水平都是不可缺

First, an overview Coal ash is the most important indicator of coal quality, coal classification, sales pricing plays a decisive role. In the process of coal preparation, ash plays a key role in directing the coal preparation, stabilizing the quality of coal and improving the productivity of washing. Therefore, it is very important to measure coal ash quickly and accurately. Low-energy gamma-ray ash measurement is only used for coal production, especially on-line or near-line measurement of coal ash during coal preparation process, which can not guide the coal preparation production, stabilize the coal quality, improve the coal yield and the automation of coal preparation lack
