Due to the dusty working environment and harsh conditions of the grinding mill, lubrication must be carried out by the lubrication table (see table) to ensure the machine's normal operation and life.

When the new machine is used, there will be iron particles falling from the bevel gear of the drive part of the machine, to prevent the machine from quickly wearing out, the oil should be changed once after 300 hours of starting, and then the oil should be changed according to the period of the lubrication table. Each time the oil changes, drain out the old oil, clean the inside with kerosene or diesel oil, and then inject the new lubricant. At the same time, pay attention to the oil level. The oil level of the spindle drive device is the oil window lower line. Do not make the rotating direction of the drive device lubricated by a spiral oil pump, otherwise, the oil pump will not work and result in bearings without oil.

The oil level of the reducer boxes of the airlock feeder and elevator as well as the fan drive box should be half of the oil mark.

The lubricating oil should be filtered before filling, and the grease nipple should be wiped cleanly to prevent dust.

 The working conditions of the grinding roller assembly are particularly harsh, so its bearing lubrication should be ensured and it should be cleaned regularly.
