Abstract

The mechanism of the friction of particles of a polydisperse material on the channel wall is considered under the assumption the friction loss of energy is caused by multiple semielastic collisions of the particles against the wall. A model is suggested for calculating energy losses in the design of the nozzles and vortex chambers of jet mills. A parametric study of the model is carried out, and the effect of particle friction on the parameters of the gas-particle flow is evaluated for these apparatuses.
