### Grinding Mill Initial Charge Calculation mss

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.

### Grinding in Ball Mills: Modeling and Process Control

2012-7-10 The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the charge in the mill and a different impact of the milling bodies on the ground material. The grinding process.
