It is a worldwide problem that dried lignite is pressed and molded. In June of this year, Luoyang Shuangyong Machine Manufacturing Co., Ltd. of Henan Province took over the world's problems with its high pressure and large pressure ball press. After successfully suppressing the dried lignite in Xinjiang and Inner Mongolia, it caused a huge sensation both at home and abroad, and found the company to solve difficult-to-press material forming. There are more and more users at home and abroad. A Russian user has heard that Luoyang Shuangyong can solve the problem of lignite forming after drying, and he has spent a lot of freight on sending lignite samples to Luoyang from thousands of miles away. Because the geographical environment of Russia is different from that of China, and it is located in a severely cold area, their lignite and lignite in China are very different. It is difficult to shape according to the lignite forming method in China. Through the unremitting efforts of Luoyang Shuangyong's technical personnel, pelletizing experts, and all members of the pellet testing workshop, the trial and error were continuously adjusted to adjust the main motor and preload motor, speed parameters and speed ratios.... After drying in Russia on July 4, the lignite was successfully pressed without additives, and the cold strength reached the user's request. Russian users said with excitement: We have found many pressure ball makers in China, and they are all helpless. Luoyang Shuangyong has helped us solve the problems and opened up a new road for the use of lignite in China. Luoyang Shuangyong took Russia's dry lignite forming problem in one stroke and solved it on July 5, 2013. After drying, the Inner Mongolia Ordos dried water-washed tobacco foam was pressed without forming additives and the cold strength reached more than 60kg. This type of foam was washed because of water and its viscosity was greatly reduced. It was difficult to shape. After many failures, the pellet technicians and the pilots summed up their experiences, thought calmly and analyzed the cause of the failure. After more than a week of trial and error, they finally succeeded. . It is understood that the accumulation of coal foam in the Ordos area is like a mountain, that is, the environment is polluted, and it is very easy to be spontaneously combusted for a long time. Luoyang Shuangyong Co., Ltd. will dry the washed tobacco smoke without adding additives to suppress the success (coal and coal block price difference is about 200 yuan per ton), that solves the pollution, transport problems, but also greatly enhance the value of coal foam, once again caused the industry Concern and sensation. The reporter learned from the China National Building Material Association that during the “Twelfth Five-Year Plan†period, along with the rapid development of China’s industry, the amount of industrial solid waste generated in the steel, coal, chemical, cement, smelting, magnesium processing, aluminum processing, and mining industries will follow. increase. At present, each mining and metallurgical enterprise in the country discharges more than 2 billion tons of waste powder and powdered tailings each year, and the total stockpile will reach 27 billion tons. If the powdered material is pressed into a ball, grain or block shape with a certain strength by a high-pressure ball press, it can be used for smelting, roasting or burning. According to a 50-per-ton increase in efficiency, it can create 100 billion yuan per year. The benefits, and can improve the environment, energy-saving emission reduction, returning land to farming, turn waste into treasure, make great contributions to the country's sustainable development.
