Abstract
An attempt is made to describe by use of the onedimensional stochastic model the flow system solid phase-liquid stirred by the mechanical rotary mixer. At the assumption that the solid phase is dimensionally homogenous a diffusion equation has been obtained which is solved under the boundary conditions, characterizing the method of withdrawal of the solid phase from the system. It is demonstrated that the model can express also the relations usually used for description of similar situations (ideal mixing, separation coefficients in stationary state etc.) like individual cases.
