Ball Mills an overview ScienceDirect Topics

3.1.2 Operation principle. The ball mill is a cylindrical drum (or cylindrical conical) turning around its horizontal axis. It is partially filled with grinding bodies: cast iron or steel balls, or even flint (silica) or porcelain bearings. Spaces between balls or bearings are occupied by the load to be milled.

Ball Mill an overview ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

Optimizing your SAG mill operation International

2007-3-21  The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the pebble removal.

This meant it was only operating at 56% of its maximum power, providing large room for improvement. The load on the ball mill was on the high side, with an actual operating power draw of 5300 kW, meaning it was operating at 90% of its maximum power. The combined power draw of the SAG mill and ball mill was 8658 kW, which caused partial over-grinding.

Ball mill circuit operation Henan Deya Machinery Co.,

2020-12-22  Gold plant ball mill circuit operation. Very often in SAG circuits, the ball-mill circuit is neglected. In many operations where economics dictate that throughput is worth more economically than the required sacrifice in grind, the focus shifts to throughput so much that the available ball mill power is not used to the fullest extent.
