fig 4 shows that after coal particle crushing the particle size distribution is dominated by particles less than 3 mm in diameter this is the case because a large number of ultrafine coal fragments were produced when the coal particles were broken by the impact of the falling 24 kg weight with the decrease of pulverized coal particle size its mass proportion increases rapidly.
