Condition Monitoring of Ball Mill with HD Technologies . There are many different types of mills; ball mills, rod mills, SAG (SemiAutogenous Grinding) and autogenous mills In a ball mill, steel or stone balls are mixed with the ore and during rotation of the drum the ore is ground, by friction and compression, into a suitable fineness for the next step in the process The main component of all
SAG mills grinding media includes some large and hard rocks, filled rate of 9% 20%. SAG mill grind ores through impact, attrition, abrasion forces. In practice, for a given ore and equal processing conditions, the AG milling has a finer grind than SAG mills. How does a sag mill work?
But monitoring the condition of a grinding mill is not a trivial task. A SAG mill is a combination of a ball mill and an autogenous mill. mills, a sufficient amount of bigger parts of ore inside the drum is critical to an effective grinding process. Get Price
SKF supplied a customdesigned heavy duty bearing housing assembly and two IMXS conditioning monitoring systems for a 12 MW SAG mill operating on a gold mine in West Africa. This is the first combination online condition monitoring system and drive train solution for a SAG mill supplied by SKF, says project manager, John Storm.
describes the coupling of single vibration sensor data from the CSIRO online monitor to the actual operating conditions of a SAG mill and how the vibration response and hence mill operating conditions vary as a function of time, including during mill equipment failures such as a broken discharge grate.
#0183;#32;This may have been the first hightech condition monitoring tool. NOT! Like Reply. M. Mark Fairbaugh. Apr 10, 2000 #8 We use electronic ears here on Sag mills. The signal is converted to 420 and goes into the PLC and is transfered to the DCS and Expert Control system.
There is strong industry interest in the development of online surface vibration (contact acoustic emission) techniques for monitoring the performance of AG/SAG mills.
With the construction of a new bioproduct pulp mill in Finland, Mets#228; Group selected Valmet DNA Machine Monitoring as an integral part of the millwide Valmet DNA automation system. As part of the machine condition monitoring application, remote diagnostic support provided by Valmet has proved to be an essential aid to predictive maintenance.
Kiln ACD is an effective tool for monitoring the operation of calciners and kilns, and for providing predictive maintenance diagnostics. In particular, Kiln ACD can be used to diag nose product ring plugging, carrying roller alignment, and thrust roller and gearbox load. It is also an ideal tool for condition monitoring.

SAG mills are primarily used at gold, copper and platinum mines where steel balls are used for the grinding. The Manta Controls Advanced Control System, called the SAG Cube, automatically monitors and controls a SAG Mill, keeping track of critical process variables impacting mill throughput.
BrainWave Control solutions for SAG mills540 . Fortunately, with BrainWave monitoring mill load, changes in feed properties are recognized quickly and action is taken before mill loadOptimal operating conditions were better maintained without the risk of mill overload.

SAG mill feeds. The benefit is that it allows the mill to process a greater throughput of ore than with a typical feed size; however, high throughput means that small changes in ore properties can cause big changes in mill loading to happen very quickly. Fortunately, with BrainWave monitoring mill load, changes in feed properties are recog
