Analyzing Kinetics of Medicated-Feed Ingredients in a Ball Mixer Mill

Abstract

Abstract Surveys were carried out to study the opportunities for increasing homogeneity of a medicated feed mixture, taking into consideration the kinetics (trajectory, speed, and vector) of certain ingredient particles in the material and airflow stream during mixing the medicated feedingstuffs and mineral-and-vitamin premixes in the mixer with a spherical chamber under the centrifugal, aerodynamic, inertial, and Coriolis forces. Separation (division or segregation) of the components in the mixture, depending on their physical and mechanical properties, such as density, particle sizes, coefficients of friction, windage, etc., occurs under the centrifugal force acting on the rotating blade surface. Leaving the blade, the material and airflow stream strikes the bottom cylindrical tank surface and, slowing down, changes its direction of movement through 90° and even 180° at the cover. In addition, the operational conditions for segregation are not limited in the applied mixers with vertical cylindrical tanks, working in the regime of fluidization. The technology and design opportunities for increasing mixture homogeneity have been revealed, since their realization in a single unit can make it possible to increase homogeneity in the medicated feedingstuff up to 95–98%.
