EXPERIMENTAL RESEARCHES ON THE INFLUENCE OF FUNCTIONAL PARAMETERS OF COMBINED SEPARATION INSTALLATIONS OF IMPURITIES FROM THE CEREAL SEEDS ON THE QUALITY INDICATORS OF SEPARATION PROCESS

Abstract

The paper presents the experimental installation, the methodology and measuring apparatus used for experimental research of qualitative indexes of impurities separation out of grain seeds for combined separating systems (according to specific mass and aerodynamic properties of seeds). The experimental installation used was composed of a gravity separator with mechanical shaker with unbalanced masses (mounted on the platform working surface) and an aspiration installation with fan. The experimental research has aimed at quantitative and qualitative influence on separation quality index of the following operating parameters: material flow rate of shaking separator, the air flow of aspiration installation, tilting work surface, work surface oscillation amplitude. Based on data obtained by measurements and qualitative indicators the separating process indexes have been determined, namely: degree of impurities separation, degree of good seeds loss),as well as, the index of technological effect for different types of combinations of separation installation parameters.
