Standard particle size distribution

Standard Particle Size Distribution

Fred Bond (1952) observed that most "conventional" comminution processes create a particle size distribution with a similar shape when plotted on log-log paper. Moreover, the product particle size distribution could be represented as a simple translation of the feed size distribution. Taggart observed earlier that the 80% passing position was a "practical criterion" for describing breakage, and Bond chose to use it as the basis for expressing this translation (though Bond could have chosen other positions such as the 50% passing, because the idealized distribution curves are parallel).
