MILL CONTROL: BALL MILL CONTROL EXAMPLE Process Description The copper concentrator in Pinto Valley, Arizona processes a 0.4% grade copper ore from a nearby open pit mine. The unit operations consisting of crushing, grinding, and flotation process about 65,000 tons of ore per day in six overflow ball mills.
The terms high-speed vibration milling (HSVM), high-speed ball milling (HTY), and planetary ball mill (PBM) are often used. The commercial apparatus are PBMs Fritsch P-5 and Fritsch Pulverisettes 6 and 7 classic line, the Retsch shaker (or mixer) mills ZM1, MM200, MM400, AS200, the Spex 8000, 6750 freezer/mill SPEX CertiPrep, and the SWH-0.4 vibrational ball mill.
31/7/1997 The dynamics of mechanical milling in a vibratory mill have been studied by means of mechanical vibration, shock measurements, computer simulation and microstructural evolution measurements. Two distinct modes of ball motion during milling, periodic and chaotic vibration
Laylabadi and Symonds  analysed the control system of an 18 MW ball mill drive system. The establishment and validation of the tumbling mill models have been widely conducted. Morrell [ 7 ] set up a power draw model of SAG mill that considers the slurry phase.

The online system Intellinova Compact with SPM HD with shock pulse measurement technique was installed for trial measurements on the autogenous mill in Garpenberg in January 2012. Between then and October 2013, two serious problems were detected well before any serious consequences: a bearing damage in one of the two gearboxes and a loose (wobbling) gear in the same gearbox.
The main problem is shock transmission, and the secondary problem is the ensuing high frequency vibration caused by the shock. Effective solutions to both problems are Fabreeka and Fabcel pads . They have been successfully used on metal forming equipment to reduce shock in the form of bumpers or mounting pads and to reduce vibration transmission as mounting pads or within a machine’s structure.
Dear Analysts, We are facing an issue on our cement plant. It's raw mill main drive motor of 4300kw. On no load condition, vibration is normal but as the feed come, vibration reaches to 4-6 mm/sec (fluctuating between 4 and 6) and whole vibration is on 85Hz (which is natural frequency of end shield bearing housing as told by manufacturer). According to manufacturer, this frequency is being
Vibration: No Elect. Discontinuity > 1μs @ 10-2000HZ, 20 G Shock: No Elect. Discontinuity > 1μs @ 50g 7945 Spring-Loaded Pin with a Standard Tail
Shock absorbers do more than prevent you from bouncing around in your seat as you drive down an uneven road. The purpose of a shock absorber is actually to help keep your tires on the ground when you're going over uneven terrain so that control of the vehicle could still be smooth and easy.
