Coal analysis - Wikipedia

The particle size distribution of milled coal depends partly on the rank of the coal, which determines its brittleness, and on the handling, crushing and milling it has undergone. Generally coal is utilised in furnaces and coking ovens at a certain size, so the crushability of the coal must be determined and its behaviour quantified.

Dec 14, 2019 · Some studies have shown that the coal particle size is different and that its specific surface area (SSA) is different, leading to varying quantities of gas adsorption and diffusion (Busch et al. 2004; Li et al. 2013). Cao et al. found that as the coal particle size decreases, the instantaneous gas desorption amount decreases.

Sep 24, 2014 · An added benefit to reducing the coal particle size is that the smaller the coal particle is, the less entrained ash-forming component in the coal particle, thus increasing flotation efficiency. The general view is that combustible recovery decreases significantly for particle sizes below 0.05 mm and above 0.5 mm [Yoon 1995 and Jameson 2007].
