how can coal be crushed to 1mm

Influence of moisture and particle size on coal blend bulk density

The bulk density initially decreases, since coal density is 1.4 g/cm 3 and the water density is 1g/cm 3.Thereby, the substitution of coal by water justifies the result found. This can also be explained by the fact that the water enables hydrophobic coal particles to repulse each other, increasing the free space and, consequently, decreasing the density.Web
