A mathematical model of continuous dissolution of salts based on a dynamic equation for crystal size distribution function was considered. A stationary solution was obtained by the moments method. For a nonstationary state, an evolution equation for the undersaturation of solution was derived. An approximate analytical method of solving this equation, which is in good agreement with the numerical solution, was proposed. The notion of the coefficient of continuous dissolution efficiency was introduced and analytical expressions for this value were obtained. The stability of the stationary solution was analyzed.
