Cooling method of ball mill main bearing
2018-04-04 | Editor:
When the ball mill main bearing works, heat is continuously transferred to the bearing from the hot material and hot gas (drying and grinding) inside the mill, and the contact surface between the bearing journal and the bushing generates heat due to friction. If not eliminated, the accumulated heat will make the bearing temperature rise to destroy the lubrication of the ball mill bearings, the allowable temperature of the main bearing lining is less than 70°C. If the bearing temperature exceeds this value, bearing-burning will occur and affect the normal operation of the mill.
Ball mill main bearing cooling methods:
1. Commonly used water cooling methods: directly lead water into the bearing bush, or use water to cool lubricant, or adopt the two methods simultaneously.
2. Directly leading water into bearing bush has obvious effect. That is to cool the bearing bush through the serpentine pipe cooling water channel cast in the spherical bush.
3. Circulating cooling water system. This method requires that there must be a casting hole in the ball mill spherical bearing bush, so that water can flow through the casting hole (serpentine pipe) and cool the ball mill main bearing. During the process, the cooling water enters through the water inlet connector, passes through the serpentine pipe and is discharged from the outlet pipe connector.
