Ball mills normally operate with an approximate ball charge of 30%.

What is a Ball End Mill?

Another benefit of the way the ball end mill is designed is that it can handle very high feed rates, meaning it can mill the material very quickly. This gives it great productivity for use in today's milling machines. The smooth geometry of the cutting tip also translates into lower cutting forces, giving the cutter added strength under pressure.

How to Handle the Charge Volume of a Ball Mill or Rod Mill ...

Ball mill charge becomes measurably swollen only when there is a buildup of large unground material in the ball mill or when the density of the pulp in a wet mill is extremely high. Although these conditions are seldom encountered, it is recommended that ball mills be ground out prior to shutdown for measurement of the charge level.
