Yuzhny Kuzbass Launches Dewatering Centrifuge at Siberia
The coal company Yuzhny Kuzbass, part of the Mechel Group, has purchased three dewatering centrifuges for the Siberia Coal Plant under the program of upgrading the processing equipment for a total value of over 25 million rubles. Chinese-made WZY-1200 filtering centrifuges have been installed in the enrichment shop of the Siberia Refinery, two of them are already in operation, the third is planned to be launched by the end of April.
This equipment is used for dewatering of 0.5-18 millimeter grade coal concentrate. The product enters the rotating rotor, and the moisture is separated from the solid product by centrifugal forces and vibration and is removed through the sieve. The use of a centrifuge makes it possible to achieve the standard indicator of 8 percent moisture content of coal concentrate without using thermal drying, which is more economical and environmentally friendly.
The productivity of each centrifuge is 120 tons of coal per hour, 70% higher than that of the previously used ones. The features of the equipment (sieve design, overhead vibrators) make it possible to significantly simplify its maintenance.
During the last year, two transformers, two separator wheels, a screen box and 27 pumping units were installed at the Sibir Central Processing Plant under the target program of upgrading the processing equipment. The purchased vacuum pump, a new magnetic separator and two drums are also helping to fulfill the set production plans for the processing of coal and the output of coal concentrate of the set parameters.
