摘要

摘要本文介绍了在实验室规模上对煤进行齿形螺旋破碎的结果。这些样品是来自俄罗斯、哈萨克斯坦和吉尔吉斯斯坦不同矿床的可销售煤炭。从粒度产量的变化分析可以发现，无论煤田位置和煤品位如何，在选煤中使用齿状螺旋破碎机进行选煤，都不会出现过磨现象。

Change in Grain-Size Composition of Coal in Toothed Screw Crushing on a Laboratory Scale

Abstract

The article presents the results of toothed screw crushing of coal on a laboratory scale. The samples are the marketable coal from different deposits in Russia, Kazakhstan and Kyrgyzstan. From the analysis of change in the quantity outputs of grain sizes, it is found that irrespective of the coal field location and coal grade, the use of a toothed screw crusher in coal preparation for dressing leads to no overgrinding of coal.
