Energy Efficiency Analysis of Copper Ore Ball Mill Drive Systems
Milling is among the most energy-consuming technological stages of copper ore processing. It is performed in mills, which are machines of high rotational masses. The start of a mill filled to capacity requires appropriate solutions that mitigate the overloading. One method for increasing the energy efficiency of ball mills is to optimize their drive systems. This article looks at two variants
PDF Technical and Commercial Benefits of Gearless Mill Drives
Typically, the synchronous motors used in SAG mills have a power higher than 10 MW. Even ball mills have a power larger than 10 MW. For this reason, they have an important impact in energy consumption and in the operation of the power distribution system. Figure 1. Picture of a typical GMD system for a SAG mill Figure 2 presents the power

The ball mill drive motor choices to the ball mill machine
3/24/ · When utility softness was a concern, the super-synchronous motor was used. In other parts of the world, the wound rotor motor was preferred. In the late 1950s, when mills approached 2500 HP, the center drive mill arrangement with the enclosed geared drive using a high-speed synchronous motor became quite popular.

Mill application features. Frozen charge protection – Detects frozen charge in the mill, minimizing equipment wear and liner replacements.; Coupling supervision – Detects if a failure or slippage occurs in the couplings and stops the system in case, preventing major damages.; Stand-still detection – Prevents the motors from re-starting if the mill is still rocking or moving after a
What is an inching drive? - Motion Control Tips
5/2/ · An inching drive is used as an auxiliary system to the main drive for a large machine such as a ball mill, industrial kiln, conveyor, or elevator. Its purpose is to turn the equipment at a speed slower than the normal operating speed — typically 1 to 2 rpm, although fractional rpms are also common — and to do so at high torque — typically
