The low-cost cleaning and classification of granular agricultural products in a vibrating environment is possible via the mathematical modeling of the movement of a grain on the surface of the screen. In this study, design and analysis of a vibratory screen used for cleaning and classifying peanuts has been realized. Therefore, firstly a mathematical model of this process has been developed based on analysis carried out on a grain making translation on a vibrating surface. A 6- bar mechanism was selected as the driving system and the kinematical analysis was performed to obtain the basic inputs of the vibratory screen. Based on the mathematical model developed, a design algorithm has been formed by which design and operating parameters are selected so as to satisfy the necessary conditions for effective sieving. This way ensures saving money and time. The algorithm has been demonstrated on a numerical example and it is shown suitable to sieve the peanut.
