moisture content

The work deals with theoretical and experimental investigations concerning coefficient of moisture pore diffusion from grain during filtration drying. To determine the coefficient of pore diffusion the model was used basing on the solution of differential equation under boundary conditions of the first type. The estimated dependence of the coefficients on heat agent temperature was obtained.

Intradiffusion mass transfer during drying of a single raw granule of slag gravel has been investigated. The physical model of moisture distribution in the single particle during its drying in the second period has been suggested. The process of intradiffusion mass transfer during drying slag gravel raw granule has been described mathematically. The effect of intradiffusion coefficient on the temperature has been studied.
