In June 19, 2018, the third largest steel group of Russia, Severstal, entitled "comprehensive upgrading of technological equipment", made a special report on the application of the Kalelisk mineral company's online testing instrument from DFMC.

Kalelisk Mining is a major producer of the North Steel Group. The mine was built in 1974 and put into operation in 1982 with an annual processing capacity of 34 million tons. The report pointed out that "in the mineral processing production, the Karelisk Mining Company lacked key on-line detecting instruments, resulting in the control of the beneficiation process was not timely." In order to increase the automatic control level of the ore dressing plant, the mine cooperated with DFMC in 2017 and introduced it in batches. PSI, IGA-D are used to transmit critical data for the production of concentrates to the controller.

Sergei Rönikov, the manager of the mining automation and metrology department, said: "the advanced instruments introduced from DFMC are like the eyes of all the people on the field, always paying attention to the production status of the site. We not only realize the detection function through the instrument, but also adjust the production of other process equipment in time according to the test data. By realizing the transmission of the test data to the controller, we have increased the production output and the quality of the concentrate. "

At present, all 12 series of Kalelisk Mining have installed IGA-D produced by DFMC. Sergei Rönikov said: “The old-fashioned Russian-made detection instruments were used on the scene. These instruments have the problems of low detection accuracy and large maintenance. The products from China DFMC do not have these problems. In addition, DFMC's technical experts also provided on-site workers with technical training."

Sergei Rönikov also added in his report: “Before the introduction of China's DFMC instrument, the mining companies deliberately arranged a visit to China to learn about the use and effectiveness of these products on a similar process site. In the future, the There is still much work to be done at Kalelisk Mining Company. We need to analyze the data received from the new equipment and establish a corresponding database."

With the help of Severstal, the installation and commissioning of various instruments of DFMC was carried out smoothly. DFMC is also willing to help more mine companies solve problems in the production process.
