OPTIMIZATION VALUE OF ANGULAR SPEED OF DRUM’S MIXTURES

The condition for increasing the uniformity of mixing by drum’s mixers is justified by uniformly distributing the material over the surface of the slurry of the mixture flowing down from the mixing blades. It is established that to completely disperse the components of the mixture with a descending stream, it is necessary that the material that falls from the blade lastly reaches the point of conjugation of the free surface of the material and drum’s shell. Developed the mathematical model for determining the angular speed of a drum mixer, in which the material completely dispersed along the free surface of the mixture segment by a flow of material from the blade. The solutions of the differential equation was used to determine the radial velocity of the particle along drum’s blade and computer simulation was performed to obtain a graphic solution of the system of equations
