How to correctly add steel balls when starting a ball mill for the first time.

When starting a ball mill for the first time, three types of steel balls - large, medium, and small - need to be mixed in a certain ratio. The proportion of large steel balls should be 30%-40%, that of medium steel balls 40%-30%, and that of small steel balls 30%. During the first addition, 80% of the recommended ball loading amount provided by the manufacturer should be used. Because after the ball mill is installed, the large and small gears need to mesh, and the processing capacity should gradually increase. After the ball mill has been running normally for 2-3 days, check the meshing condition of the large and small gears. Once everything is normal, open the cover of the ball mill hole, and add the remaining 20% of steel balls for the second addition.
