To optimize the energy consumption of the mill, Siemens has developed a new mill control system. The first pilot project involved one of the four ball mills at the Rohrdorf plant. Dating from 1965, this mill consists of two chambers: the first chamber is filled with large steel balls, and the second with smaller balls.
cently, ball mills are also being cons idered. This work addresses s ome current issues involving d esign and application of high-pow er drives employe d in SAG grind-
The modernization project includes two 8 MW SAG (semi-autogenous) mills and two 9.7 MW ball mills with dual pinion drives. The new drive systems are replacing the existing synchronous motors and direct converters for the SAG mills and the drive systems of the ball mills, which were installed by a different manufacturer.
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball …

The Ballbar test will measure any deviation the machine makes from a perfect circle, recording data as the two axes work together. Errors such as backlash, level/squareness, servo mismatch, reversal spikes, vibration, stick slip and other problems can be determined. Users can be useful in determining what feedrate delivers the best accuracy by ...
Larger ball and SAG mills, with higher installed power ratings relative to the mill diameter, offer higher efficiency and throughput, round-the-clock reliability and the opportunity to mine in remote areas. This makes low ore grades economical to grind. ABB has delivered some of the world's largest GMDs: • 22 MW GMD for 28' ball mill
Siemens, the company that introduced Gearless Mill Drives (GMD) to mining industry started up its first GMD on a ball mill in Norway in 1980. The mill and its drive system are still in service. Today, GMDs are mainly used for SAG mills between 36 and 40 feet (10.7 to 12.2 m) and ball mills from 24 to 28 feet (7.3 to 8.5 m).

There are basically two methods of producing nano-scale particles: the "Bottom-Up" technique involves synthesizing the particles from atoms and molecules. With the "Top-Down" method the particles are reduced to nanometer size by grinding. Suitable tools for this method are planetary ball mills, such as Retsch's new PM-series grinders, which provide the necessary …
