The paper presents the results of experimental studies of the shape and polydispersity of particles of cyclonic oil shale, unclassified and classified ESP ash and classified cenospheres obtained from combustion of Kuznetsk coals at Belovskaya SDPP. The shape and polydispersity factors of particles of the studied bulk solids are developed.
The dependence for estimating critical velocity of dust and air flow at pneumatic conveying of fine polydisperse materials with regard to particle shape and polydispersity is verified.
