Abstract: With the development of the economy, the country’s demand for mineral resources is becoming more and more large, so that the processing plant will continuously expand the production scale and improve the production process to meet the needs of the economy and society. The Chifeng NFC Baiyinnuoer Mining Co., Ltd. Actively respond to the national call to improve the process of the production of the production process, the amount of processing is expanded by the current 3 000 t/d to 5 000 t/d, and the corresponding process equipment will be upgraded accordingly. However, the current use of the electromagnetic valve reagent feeder system is disabled because of the lack of additive quantity and low accuracy, and the mining factory urgently needs a automatic reagent feeder system that can achieve the addition of the reagent, high precision and small maintenance quantity. In order to solve the difficulties encountered in the mining factory, BGRIMM has designed the BRFS metering pump reagent feader system based on the actual demand of the mining factory. The system has been used in the industrial application of the mining factory for three months, which has solved the problem of automatic addition of the reagent, which fully meets the needs of the processing plant and has brought considerable economic benefits to the processing plant.
