1. Mill diameter refers to the diameter inside the mill shell, while the mill length refers to the distance between two flanged ends. Effective grinding length is determined by the sizes of end liner and grate. Effective volume is the available volume inside the mill excluding the volume of shell liners and end liners, but the volume of two end cones is contained.
2. The particle size should not greater than 350mm.
3. The maximum ball loading capacity of AG mill is calculated at 3% of effective mill volume, while the SAG mill with ball loading capacity at 15% of mill volume.
4. The operating speed is usually 75% of critical speed of mill, the variable frequency speed regulation is ideally somewhere between 5% to 10% of rated speed.
