Abstract. Of all types of dosed mixture preparation equipment, continuous flow dispensers have a number of significant technical and economic indicators compared with cyclical equipment. The most promising continuous flow dispensers with flow control. They have a high accuracy in supplying the mixer with the specified components, which determine the capacity of the installation. In these batchers, an optimal type of control is used, using the method of changing the speed of the conveyor belt, which allows for a uniform feed of the material and a wide range of regulation. The structural block diagram of automatic control of the linear speed of conveyor belt movement is provided, which ensures optimization of the specified productivity of the dispenser with a minimum error.
Key words: continuous flow dispenser, weighing conveyor, loose material, measurement error, automatic control, primary converters for controlling the mass of material and linear speed of the conveyor, frequency converter, transfer functions of the control system.
