| The carbon seal ring 20MG50.11.06.97 of the coal mill plays a vital role in the medium-speed coal mill. Its main purpose is to achieve the sealing between the inside and outside of the coal mill and prevent the leakage of hot air and coal powder. The carbon seal ring is usually installed in the annular groove of the sealing shell of the coal mill base, with its inner circular surface in contact with the transmission shaft and the outer circular surface embedded in the transmission disc groove. During operation, the carbon seal ring can effectively isolate the hot air inside the coal mill from the outside atmosphere to ensure the stable operation of the coal mill. The carbon seal ring 20MG50.11.06.97 has excellent high temperature resistance and self-lubricating properties, which enables it to operate stably for a long time under the high temperature conditions of the coal mill. In addition, the material of the carbon seal ring is usually a graphite matrix, which has good mechanical strength and wear resistance after a special impregnation process. This kind of seal ring can maintain a good sealing effect under the complex working conditions of the coal mill, reduce coal powder leakage, and reduce energy consumption and environmental pollution. Therefore, the carbon seal ring has become an indispensable key component in the medium-speed coal mill of the power plant. |
