This article reports results of a calculation of the stress-strain state of the body of the drum of coal pulverizers using a method developed at the Institute of Mechanics to solve problems of shell statics. The method has been successfully used for several years at a pipe construction plant to design drums for ore crushers. The design diagram of the body of the coal pulverizer drum is shown. Numerical calculations of the stress-strain state of the drum of an Sh-50A coal pulverizer shows good convergence of the results with the summation of six to ten terms of the series. The calculations make it possible to model the stress-strain of the entire drum and select design parameters which are optimum from the point of view of strength and rigidity.
