摘要

本文对湖南某地区常用煤种进行了混煤可磨性和磨损性分析

通过试验研究了两单煤按不同比例混合后

混煤的可磨性指数和磨损性指数的变化趋势。试验结果表明

混煤的可磨性指数和磨损性指数不能简单通过各单煤的加权平均值计算获得

实测值和加权值之间存在一定的差异。

Abstract

In this paper

the grindability and wear index of blended coal are analyzed

and the changing trend of grindability and wear index of blended coal after mixing two single coal in different proportions is studied by experiments.The results show that grindability and wear index of blended coal can not be obtained simply by calculating the weighted average value of each single coal

and there are some differences between the measured value and the weighted value.
