This paper presents a mathematical model for the calculus of the necessary shifting power of the radial blades mixers for solid granular products. For the radial blades inclined up to the rotor rotation axis they are writing the relations of the material particles speed, axial and tangential, for the case when it is neglected the friction and for the case with friction, also the resistance forces at moving material on the two considered directions. It is writing the general relation for the calculus of the shifting power and it is ratifying the mathematical model through illustration on an available radial blades mixer.
