【Ten Years of Rapid Development in Chemical Processing Equipment】The Largest Ball Mills in the Coal Chemical Industry from 1999 to 2019

Thread Content

Ten years of rapid development in chemical processing equipment – praise for China’s prosperity and strength. This is just a starting point; more participation from everyone will make things even more lively. HaiChuan becomes even better with your involvement; we welcome everyone to join in the forum discussions. Have a happy weekend! ********************************************* The ball mill used in the gasification unit of the Inner Mongolia RongXin project, which is under the general contract of Hualu Technology Company affiliated with China National Chemical Corporation, passed its single-unit test successfully, laying a solid foundation for starting up the gasification unit and beginning trial production in October. This is the largest ball mill in China’s coal chemical industry at present. The ball mill is one of the core equipment in the gasification unit, used to grind the coal lumps delivered from the coal preparation unit into coal powder. The project features 4 overflow ball mills, breaking with the previous practice of using rod mills in coal chemical projects; this approach improves the fineness of the coal powder and extends the service life of the mills. The specifications of the ball mill drum are φ5.2*8.5m; the motor’s rated power is 3800kW. The loading capacity per mill for steel balls is 252 tons, the solid concentration ranges from 56.5 to 65 wt%, and the density of the coal slurry is 1150–1250 kg/m3. The production rate per mill is 131 t/h (on an air-dry basis).
