The results of measurements of length, width, area and perimeter, reduced diameter of five samples of black SiC grains 54СF60 obtained by sieving on control sieves are showed. The characteristics of the distributions of the parameters, the relationship between them and the mesh size of the test sieves are determined. Found that the normal distribution is subject to the width of the distribution of grain, except for the fine fraction (residue per pallet), then reduced diameter (three fractions) and the projected area of the grain profile on the horizontal plane (two fractions). Distribution of the length and grain length to width do not obey the normal law. As a result of classification on the needle grains isometric and intermediates found that the content of acicular grains from 3 samples to the sample 6 is increased about 5 times, while the content of isometric grains decreases 2.7 times.
