supported grinding mills up to the largest sizes. SAG/ball mill circuit incorporating pebble crushers and a POLYCOM® high-pressure grinding roll. SAG and ball mill for gold ore grinding. One of three SAG mills with 9.75 m diameter and 2 x 4000 kW drive power. These mills operate in conjunction with ball mills for iron ore grinding in Iran.
SAG Mill Power. SAG milling can be optimised to achieve maximum breakage and throughput (or any other number of objectives). The relationships between the key variables are highly non-linear and shift as the ore hardness, steel load and liner conditions change.
Mill Vibration Phenomena during Cold Rolling. All machines vibrate during operation. However, only a few of these vibrations cause problems to the product or the machine itself. Typically, the most damaging vibrations involve a natural resonance of the machine which significantly increases the motion of critical components.
The process state of an AG/SAG mill can be inferred from surface vibration monitoring. This is a passive, non-intrusive, low cost and reliable hardware monitoring technology that is sensitive to ...

OPTIMAL SAG MILL CONTROL USING VIBRATION & DIGITAL SIGNAL PROCESSING TECHNIQUES ABSTRACT 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.
We have found nothing mechanically wrong to relate to this problem. The vibration has high energy, Time wave forms are sinusoidal and not impactive. I have tried to relate this frequency to other parts on the Sag Mill with no luck. This is why I come back to the motor. Will upload the vibration .
