description	The utility model relates to a milling bearing sealing device of a coal pulverizer of a roller disc type, which is applied to the technical field of milling equipment and wholly comprises a rolling bearing, sealing rings, frame seals and a milling bearing, wherein the rolling bearing, the sealing rings and the frame seals are mounted on the milling bearing. The utility model has novel and scientific conception and adopts nitrogen or pressure air of 10 kpa to 20 kpa in a usual amount of 20 m /h to 100 m /h instead of a great amount of pressure wind so as to ensure the safe operation of a coal pulverizing system of high-volatilization bituminous coal or wood coal, improve the thermal effect of primary air (dryer), simplify the structure of the coal pulverizer, and reduce the maintenance and overhaul amount.
