These equations represent a best fit of data from 39 experiments on impact crushing of quartz particles ranging in size from .156 to 5.75 cm in diameter. The standard error for Δx is .387 as compared with 1.192 for the observed data. The form of the distribution curve was found to be primarily a function of the size reduction.
