Abstract
Number of grains per unit weight of the powder grinding is counted with all its fractions obtained according to GOST R 52381-2005 sieving on control sieves. The number of grains counted manually after weighing grain samples on analytical scales. A comparison of these data with studies of grinding powders obtained by outdated standards on grain composition is done: GOST 3647-80, GOST 3647-71. To verify the published formulas we measured the length and width of grain fractions of grinding powders.
