近几年,我国内蒙古地区以及东南亚发现大量褐煤资源,这些褐煤的含水量在35%左右,超出了低、中速磨煤机的正常磨制范围。2005年沈重从俄罗斯塞斯兰重机厂引进了大型的MB系列风扇磨煤机,用以磨制水份在40%以下的褐煤。
In recent years, a large amount of lignite resources have been found in Inner Mongolia and Southeast Asia in our country. The moisture content of these lignites is about 35%, exceeding the normal grinding range of low- and medium-speed pulverizers. In 2005 heavily from the Russian Sisiran heavy machinery factory introduced a large MB series fan coal mill, used to grind water 40% of brown coal below.
