Recent developments in low power wireless and Digital Signal Processing (DSP) technologies have given rise to a new system that can monitor vibrations in real-time on the rotating surface of SAG, AG, and Ball mills. Specifically designed for the SAG mill, a new device is presented that digitizes and processes vibration from three key points on the …
The basic strategy works by maximizing the SAG mill power, using a microphone or vibration sensor on the shell to indicate when the impact energy is low, and when the …
For SAG Milling, optimizing the throw and converting the available electrical energy (installed motor power) to potential energy (height of throw, trajectory) to kinetic energy (rock breakage) is the key function. …
The mill operator then needs some way of balancing the distribution of this critical sized material between the primary and secondary mill as an onstream operating control. This would allow the operator to adjust the workload between the primary and secondary mill as the ore changes so one will not be overloaded and the other underfed.
