At present, although the torch of the Beijing Winter Olympic Games has been extinguished, the passion brought to us by some inspirational and moving Winter Olympic stories is still continuing. In just 17 days, we have seen: the confidence of big countries in the opening and closing ceremonies, the courageous struggle of Olympic athletes, and the Olympic spirit of faster, higher, stronger and more united!
If there is Winter Olympics in coal preparation industry, who will win the champion? As the "National team" - Shenzhou group, which won the second prize of the national scientific and technological progress award by virtue of "key technology and application of high-efficiency dry coal separation ", what will be the dazzling performance?
The ultimate interpretation of the speed and passion on ice and snow. ZM series Alpine dry coal separation equipment of Shenzhou group has the strength to fight!
In view of the fact that coal in cold areas cannot be washed and processed in winter, Shenzhou group has developed an alpine dry separation system suitable for coal separation in cold areas. The system adopts special layout structure and thermal insulation measures to completely solve the problems of coal freezing and pipeline blockage in cold areas.
EXTRAORDINARY PRESENTATION: BAIYINHUA NO.3 COAL MINE IN INNER MONGOLIA
Baiyinhua No. 3 coal mine dry coal preparation plant, with a design capacity of 6.0mt/a, is built in an open pit, and it takes only 70 days from construction to operation. It is mainly used for full size separation of residual coal and low calorific value coal in the pit. The calorific value of raw coal is 2937kcal / kg, and the calorific value of cleaned coal after separation is increased to 3524kcal / kg. Dry coal preparation not only improves the calorific value of coal, but also reduces the stock of residual coal and reduces the risk of spontaneous combustion, which has brought huge economic and social benefits to the mine. It is also a very large underground dry coal preparation plant in the world.

EXTRAORDINARY PRESENTATION: HEISHAN COAL MINEOF XINJIANG ZHONGTAI CHEMICAL SHENGXIONG ENERGY GROUP
The coal in Heishan coal mine is mainly long flame coal and non-stick coal. The tar content is up to 18.6%, which is the best raw material for coal to semi-coke. The average altitude of the mining area is more than 2000 meters, which belongs to continental arid and alpine climate, so the traditional water preparation method cannot be used. After that, ZM400 plateau dry separation system is selected to discharge gangue and improve the quality of 80-20mm mixed lump coal. The gangue content of cleaned coal is controlled within 2% ~ 5%, which fully meets the needs of semi-coke plant.

EXTRAORDINARY PRESENTATION:MAIRYKHSKY OPEN PIT MINE LTD
Mairykhsky open pit coal mine is located in Siberia, Russia. The coal type is long flame coal with an average calorific value of 5100kcal / kg. A 6.6mt/a dry coal preparation plant will be completed and put into operation in April 2019. The calorific value of the selected products will be stable above 6000kcal / kg, and all of them will be used for export sales. The dry coal preparation plant is completely free from the restriction of water source and the influence of winter alpine climate. It operates continuously and stably throughout the whole year, which not only ensures the stable users in the international market, but also improves the economic benefits of the coal mine.
Despite the complex and changeable extreme cold working conditions, Shenzhou group has a complete set of solutions to meet the diversified and personalized needs of customers in an all-round way. In the global arena, it presents the technical route of "replacing water with wind, dry coal preparation, energy conservation and environmental protection" and the quality of "Olympic grade" products.
The same "China Red", the same glory for the country and the pride of the country - Shenzhou group!
