Operating and Maintenance Guidelines for Screenbowl

Jan 12, 2009  Since first being introduced to the coal industry in the late 1960s, screenbowl centrifuges have become the most common method for dewatering fine coal. Since that time, the machine has developed a well-earned reputation for providing a better reliability and lower product moisture than competitive technologies such as vacuum filters.
