Coal comminution and sizing
F = Material weight factor, accounting for the change in feed density. The standard is 100 pounds per cubic foot (1600 kg/m 3), but the bulk density of coal is typically closer to 50 pounds per cubic foot (800 kg/ m 3). The factor F for a typical coal would therefore be 50/100 = 0.5. G = Open area correction factor.
