A pile of particles(micro and nano) act as a system where the big particles feed power to the little particles. It is like a multi stage rocket where the big stage feed power to the smaller stage.
At the end of the line, the smallest stage has a huge amount of power built up from all the bigger fellows down the line of contact. The bigger the pile and the broader the particle size differences, the more power is fed to the smallest particles in line.
