В результаті теоретичного аналізу отримано функціональну залежність швидкості руху зерна по гравітаційній направляючій поверхні з урахуванням опору повітря, а також графічне зображення її форми. One of the factors that greatly influences the grain separation process is the speed of its supply and the direction. The peculiarity of the work of the studied aspirating channel with the multilevel grain supply is that its feeding device consists of several guiding surfaces, which are situated above each other. The length of the guiding surfaces increases along the path of the grain material, which is caused by the construction necessity. For the effective work of the studied aspirating channel the speed of the grain supply on all guiding surfaces of the feeding device should be equal. So, for provision of the chosen speed regime of the grain movement there is a necessity to prove the correspondent form of the guiding gravitation surface. As a result of the theoretical analysis there was received a functional dependence of the speed of the grain supply on the whole guiding surface taking into account the air resistance and graphical image of the form of the guiding surface of the air separator feeding device.
