THE MEASUREMENT OF PARTICLE SHAPE

ONE METHOD IS BASED ON THE DEPARTURE OF THE PARTICLE SHAPE FROM A PERFECT ELLIPSOID, ALLOWANCE BEING MADE FOR SURFACE TEXTURE ACCORDING TO THE ANGULARITY OF DEPRESSIONS AND PROTUBERNACES. ANOTHER EMPLOYS THE MINOR DIAMETER AND A SHAPE FACTOR, BUT IT IS NOT CONSIDERED AS SATISFACTORY AS THE FIRST METHOD. EXPERIMENTS SHOWED THAT LIMITING POROSITIES OF SAND ARE RELATED TO THE SHAPE FACTOR. /RRL/
