VNaughtTCosTheta. • 6 yr. ago. Assuming there is no size distribution and just one size, my intuition is that particle size has no effect on bulk density if you ignore boundary effects. Particle size will change boundary effects though, which will impact bulk density. Obviously bulk density will change if you have a particle size distribution. 4.
