The variety of applications being tested and operated are ...
In this study, each of these methods was applied before ball mill grinding to investigate its effect on enhancing the liberation of copper minerals in a fine-grained, low grade copper ore. The copper minerals are chalcocite, bornite, and chalcopyrite and their grain sizes range from 10-500 µm. The gangue minerals are calcite, quartz, and feldspar.

Case study. Musim Mas operates globally across the palm oil business. It owes the biggest palm oil refinery factory of the world. In this project it needed to get the bentonite powder in 0.1-0.3mm and the capacity of 3 tons per hour. Solution. According to the requirement, we recommend them to use the ball mill for this project.
recycle crushing would relieve the SAG mill restriction, allowing throughput to be maintained and ensure that good energy efficiency could be maintained. Notable Feature When the modelling was completed, the existing circuit was found to swing between being SAG mill limited and ball mill limited, depending upon the ore blend being treated.

Paper # 25 Copper Mountain Overview on the Grinding . Typically a dedicated inching drive will turn the mill at a speed of about 0.15rpm. In the case of Copper Mountain, the inching mode in the ABB drives are currently set to turn the SAG mill at about 10 % of rated speed and the ball mills at about 3% of rated speed (mill speed 0.40 rpm).
The IsaMill is a stirred-medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.
