AG mills (or SAG mills with low ball charges) are often used in singlestage grinding applications. Based on their higher throughput and coarser grind relative to AG mills, it is more common for SAG mills to he used as the primary stage of grinding, followed by a second stage of milling. AG/SAG circuits producing a fine grind (particularly ...
Using the Benshaw Low Voltage Drive for positioning a MV synchronous motor driven ball mill is another great solution. The Benshaw variable frequency drive powers the 4160v synchronous ball mill motor during positioning to smoothly rotate the ball mill, providing full torque at zero speed to start and rotate the mill during the positioning process.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium.
The original ball load in the mill was 6614 lb. (3000 kg.) and the load at the end of the 694 hr. was 6338 lb. ( kg.). During this time, 590 lb. ( kg.) of balls less than 3 in. ( mm.) in diameter were discarded from the mill. The screen analysis of the ball charge at the end of the operation is shown in Table 20.

Motors considered are the squirrel cage motor, wound rotor motor, and synchronous motor. One important advantage of the synchronous motor is the possible correcting of power factor within your operation, through its use. When using a synchronous motor we recommend having 200% starting torque, 120% to 130% pullin torque, and 225% pullout torque.
