coal crushing required

The normal preparation procedure requires that each air-dried coal sample pass through a jaw crusher; one subsample (split) of the crushed material (2 to 4 mm, or 5 to 10 mesh) is then taken for the ultimate and proximate analyses, and another split is reduced to approximately 150 m m (100 mesh) by a vertical grinder for chemical analysis

    Apr 30, 2021 Abstract Determination of the coal-strength coefficient in accordance with State Standard GOST 21153.1–75 is clear and simple. No complex equipment is required, and capital expenditures and energy costs are relatively low. This method satisfactorily reproduces the crushing conditions of coal in hammer systems, and the granulometric composition of the ground sample is close to industrial
