Generally, the newly installed ball mill has a running-in process. During the running-in process, the amount of steel balls is added for the first time, accounting for 80% of the maximum ball load of the ball mill. The proportion of steel balls can be added according to the size of the steel balls (ф120mm, ф100mm, ф80mm)., Ф60mm, ф40mm).

Ball mills are horizontal rotating cylindrical or conical steel chambers, approximately one third to half full of steel, alloy steel or iron balls, like that shown in Fig. 4.10 A–C, or flint stones. The size reduction is accomplished by the impact of these balls on the material as they fall back after being lifted by the rotating chamber.
A ball mill is a cylindrical device that rotates around its axis, partially filled with the material to be ground plus the grinding medium (usually ceramic balls, flint pebbles, or stainless steel balls). As the mill rotates, the grinding media crushes and grinds the material against the inner surface of the mill chamber, creating a fine powder.
