A typical SADR-1 system implemented by JSC Soyuztsvetmetavtomatika im. Topchaeva V. P. at the SASA DOOEL Mine processing plant (Macedonia) is presented, and the components included in its structure are considered. The functional purpose of technological feed tanks and the features of their operation are given. A block diagram and a diagram of the operation of the system for automatically maintaining the average level of reagents in tanks are presented. Methods of continuous and pulsed dosing of reagents are considered, namely: batch and pulse width (PWM) pulse dosing methods with an assessment of methods for calculating the average reagent consumption, as well as the advantages and disadvantages of these dosing methods. The description and operation scheme of the BSU-1 unit, which provides pressure stabilization at the inlet of the dosing valve, ADI-1 pulse dispenser units, PRIU-5M and PRAU-1 reagent feeders with URIP-6 tables, as well as a fragment of the dosing unit of the Steel Group Laiwu Mining CO (China) processing plant are given. A description and diagram of the operation of the unit for generating a twostage control signal for medium and high flow feeders, which implements an energy-saving mode of energy consumption by an electric valve. The control of the dosing process is considered in detail using the example of the upgraded UDR-16M2 device. Its composition is given, the implemented functions and modes of operation are described. The main visualization screens “Dosing Control screen” and “Accumulated flow display screen” are stated. The competitive quality of the distributed SADR-1 system in comparison with grouped devices from other manufacturers is substantiated, as well as the successful implementation and operation of the SADR-1 system both at processing plants in Russia and at facilities near and far abroad.
