宝日希勒褐煤及其半焦制品的可选性分析

Washability analysis of Baorixile lignite and semi-coke of the lignite

摘要: 通过试验分析了宝日希勒褐煤及其半焦的可选性,结果表明:宝日希勒褐煤及其半焦是可选的,采用褐煤制备半焦,再对半焦进行分选,可获得多种半焦产品;并且,褐煤在制备半焦的过程中易发生碎裂,使得半焦的粒度上限小于褐煤的粒度上限,有利于半焦的洗选加工。

Abstract: The article analyzed the washability of Baorixile’s lignite and semi-coke through experiment.The result shows that the lignite and semi-coke can be separated in theory.The semi-coke prepared from lignite,and then separation the semi-coke can get a variety of semi-coke product.Besides,due to the lignite broken during the preparation of semi-coke,so the upper limit of particle size（13 mm） of semi-coke is less than that of the lignite’s（50 mm）,which can be beneficial to separate semi-coke
