Fractal characteristics of crushed particles of coal ...

2017-1-1  The particle size gradation of the two gangue specimens exhibited fractal characteristics after manual crushed, and the fractal dimension of each crushed specimen ranged from 0.352 to 2.654. (2) Regarding sandstone and sandy mudstone, the fractal dimension D of specimens with particle sizes from 20 to 31.5 mm and 31.5 to 50 mm rose quickly at ...

2018-2-3  Figure 1 shows size by size cumulative float curves for the Batac jig feed. It can be observed that each size fraction has different washability characteristics as manifested in the float curves. The curves from right to left indicate better washability characteristics with superior yield of clean coal at a specified ash content, e.g. 18% (typically 17–19%), as generally targeted by the plants.

ISO 23499:2013(en), Coal ? Determination of bulk density ...

This International Standard provides description of a cone procedure for determining an uncompacted bulk density of crushed coal less than 37 mm in size, such as is charged into coke ovens. It focuses on the uncompacted bulk density of coal resulting from flowing the material into a measuring container (box) in the absence of compacting forces.

Coal Density - an overview ScienceDirect Topics

Coal density is among the important parameters for reservoir engineering purposes and is inserted as an input property in simulation studies. Coal density is typically less than that of conventional reservoirs and differs from seam to seam based on the given coal rank and purity [2].The bulk density of a coal consists of the matrix and the void space, with the latter being expectedly filled ...
