In addition surveys were conducted on an E-mill in a power station of a Chinese energy and chemical manufacturer, and a CKP mill in a Chinese cement plant, with only mill external samples collected. A total of 33 plant surveys were completed at various operational conditions, requiring 475 man-days at site from the JKMRC and CUMT teams.Our ATOX® Coal Mill is a compact vertical roller mill that can grind almost any type of raw coal. The coal mill utilises compression and shear force generated between the large rollers and the rotating table to crush and grind raw coal, removing the need for a separate piece of equipment for crushing. The coal mill can also grind petroleumATOX® Coal Mill FLSmidth
