Population growth in the last 20 years and also diversifying people’s food needs have led to an increased demand for products obtained from animals raised on zootechnical farms. For maintaining in the profile market, by providing quality products at the lowest price, the combined feed factories were equipped with modern work equipment and installations to ensure a high degree of mechanization, automation and computerization of the activities performed. This had favourable consequences in achieving high productivity with low specific consumption. The technological flow carried out in a combined feed factory involves performing several activities, such as: supply, transport, grinding, mixing, granulation, cooling, packaging and storage. Thus, a very important activity in a combined feed factory is the transport of raw materials from warehouses to work facilities. To ensure proper functioning of work facilities and an increase of labour productivity, the implementation of automated control of conveyor belts is recommended. The experimental investigations were based on the achievement of an electronic device, through which the operation of magnetic rotation and proximity sensors was monitored. These types of sensors equip the automatic control devices for conveyor belts used in a combined feed factory. The electronic assembly realized in own conception allowed to determine with accuracy the values of the response times, as well as the distances required for automatic shutdown of the transport system. In case of overload, this automatic shutdown command is of major importance in order to avoid the destruction of the transport system. The obtained results demonstrate the functionality of the designed command and control system, as well as the need for its implementation to ensure automated monitoring of the transport of raw materials between the work facilities.
