Mean Particle Size Variations due to Heap Sampling.

Abstract

This study illustrates that the measured weight median diameter of HMX ground by fluid energy mill (FEM) is influenced by the location in the heap from which the sample is withdrawn. Three samples were selected from the top, middle, and bottom of the FEM collection heap. An analysis of variance illustrated three distinct populations of HMX with 95% confidence. All samples had residuals which were normally distributed about zero, indicating no gross systematic errors occurred. The weight median diameters obtained for the three samples from a single grind were 33.6, 30.0 and 36.6 microns for top, middle, and bottom samples, respectively.
