| The Coal mill graphite carbon seal ring MG50.11.06 is installed in the annular groove of the sealing shell of the coal mill base. Its main function is to isolate the hot air inside the coal mill from the outside atmosphere, prevent the outside air from entering the coal mill, and also prevent the hot air and coal powder inside the coal mill from leaking into the external environment. During operation, there is no lubricant between the drive shaft and the sealing ring, so the Coal mill graphite carbon seal ring MG50.11.06 needs to have good self-lubricating properties to reduce wear and ensure the normal operation of the drive shaft. The Coal mill graphite carbon seal ring MG50.11.06 needs to withstand the high temperature environment inside the coal mill, usually the temperature does not exceed 400, and it must also be able to withstand the low temperature environment outside, generally requiring it to withstand a low temperature of -20. Due to the presence of coal dust particles inside the coal mill, sometimes containing water or water vapor, the Coal mill graphite carbon seal ring MG50.11.06 needs to have a high anti-wear performance to ensure long-term stable operation under these harsh conditions. It is usually required to be able to meet the continuous and reliable operation of the coal mill for more than 8,000 hours. |
