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.
