w to sense the coal particle size while crushing

4.2.1 Effect of particle size on charge bulk density. When particles are divided, the total surface area and the number of voids between the particles are increased (), reducing the density because the coal volume increases, justifying the results for an excessive crushing at 85% 2.83mm.The reason for misunderstanding: the resolution limit of the human eye at a distance of 25 cm is 0.2 mm ...
