In this article some experimental studies were performed in order to analyze some physical parameters specific for a solid particle during displacement in a vertical air flow. The analyzed parameters were the instantaneous average velocity value and the angular velocity value. To determine the two parameters, a laboratory stand was used for the aerodynamic separation of a mixture of solid particles and a high-speed video camera in order to be able to track the behaviour of the studied particles. At the same time, a working methodology has been designed, implying the use of multiple software, i.e. analysis, video, imagistic and date software, methodology that aims to convert a video file, where we have a 2D view, into a 3D interpretation. Following the analysis of the obtained results, we noticed that both the instantaneous average velocity value and the angular velocity value are closely linked to the sphericity of the solid particle, varying inversely proportional to it, and to the air flow velocity, which directly influences the analyzed parameters.
