Principle
The main bearing is a key component of the Overflow Type Ball Mill. It must pay full attention to its lubrication. It is generally concentrated and lubricated with thin oil. The oil flows through the pump into four parts and is pressed into the main bearing and the transmission bearing, and then discharged to the bottom of the bearing. The pipe then flows back to the tank. For medium and small ball mills, oil ring automatic lubrication, oil cup oil lubrication or solid lubricants are used. Some concentrators are equipped with an automatic oil-breaking alarm device to ensure the reliability of lubrication. The overflow ball mill is supported on the main bearing by a hollow shaft at both ends. One of the two hollow shafts is axially stretchable on the main bearing and the other is fixed. Since the gearing of the ball mill produces a directional force, a hollow journal is designed with two shoulders, and the distance between the shoulders is exactly equal to the length of the bearing bush to prevent axial movement. The other hollow journal has no shoulders and its length is greater than 5-25 mm for the length of the bearing bush. When the cylinder is heated to elongate or the cylinder is flexed due to the load, it can freely expand and contract within a certain range.
