Vibration is most commonly measured using a ceramic piezoelectric sensor or accelerometer. An accelerometer is a sensor that measures the dynamic acceleration of a physical device as a voltage. Accelerometers are full-contact transducers typically mounted directly on high-frequency elements, such as rolling-element bearings, gearboxes, or spinning …
Choosing vibration monitoring methods. Grinding mill finds continuous online surveillance of vibration to be cost-effective after conversion from offline system. SEMIAUTOGENOUS GRINDING mills, also known simply as SAG mills, grind materials from large chunks into small, usable pieces for processing. The ones used in mining operations in Canada ...

variability) and surface vibration signal (intensity, sensitivity and operation variability), between this type of primary grinding mill and AG/SAG mills. MILL MONITOR SYSTEM AND RECENT ENHANCEMENTS. The key features of the original prototype of a ruggedized continuous mill monitoring system were described in Campbell . et al (2006).
The Perfect Pair: Shock Pulse and Vibration Monitoring Combo Pays Off at Boliden Mine. ... A SAG mill is a combination of a ball mill and an autogenous mill. The main component of all mills is a horizontal rotating drum, typically with a rubber liner and regularly spaced lifter bars (see Figure 1). Generally, the ore is continuously fed into ...
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 …
vibration and plant operating data such as flow, temperature, or pressure. Continuous monitoring detects the onset of component problems in advance, which means that …
The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

This paper will show the advantage of an on-line continuous vibration monitoring compared with the regular surveys using portable equipment. It will present two case studies of detecting bearing faults in a Semi Autogenous (SAG) Mill on a mining side; one in …
Vibration Monitoring Asset Monitoring Overpressure Protection Anti-Surge Technology ... The SAG mill's motor – a critical piece of equipment – must be monitored for temperature. ... monitoring temperature trends to prevent overheating and unexpected shutdowns. This solution can be easily and quickly installed with minimal downtime.
There is strong industry interest in the development of on-line surface vibration (contact acoustic emission) techniques for monitoring the performance of AG/SAG mills.
Complete Monitoring Solutions. The online monitoring of a large Ball or a SAG Mill provides vital information on the health of the machine. More than just protection, VibroSystM provides ZOOM users with autonomous data analysis and first level diagnostics that are both predictive and preventative, which will significantly reduce machine downtime.
The SAG mill's motor – a critical piece of equipment – must be monitored for temperature. This is essential for avoiding costly, unexpected plant shutdowns as well as high service and parts costs.
Surface vibration (acoustic emissions) monitoring is a noninvasive low-cost means of monitoring normally inaccessible attributes of processes or equipment operation. The current …
Thus, with condition monitoring of the SAG mill behaviors employing vibration, acoustic and thermal signals, the relevant parameter can be diagnosed and monitored. …

Online Vibration Monitoring System Improves Fault Detection in a SAG Mill. Though we never failed to detect actual failures, there were other things going on: overheating, noise, etc. When those issues arose, we were called to the mine to check the equipment. Of course, this would happen at the most inconvenient times...
Online Vibration Monitoring System Improves Fault Detection in a SAG Mill. A copper mine site already had an extensive condition monitoring program in place. We went through their oil analysis reports regularly, sitting down with them and going through the possible faults. Every mine site has several critical machines.
This non-invasive vibration monitoring and expert system generates both build-up and blockage alarms to help detect and predict blockages immediately to prevent equipment damage and respond quickly. SAG and Ball mills are one of the most critical pieces of equipment for mining processes. Operators need to optimize grinding mill performance and ...

Vibration Sag Mill Motor NDE Bearing. At our mine we have an issue with vibration at the Sag Motor NDE bearing. The bearing is a journal white metal bearing. The motor has been running for about 14 months now. The vibration at the NDE bearing was around 2mm/sec. In the last month it has climbed to 4.5mm sec with the dominate frequency 1x RPM.
