AG/SAG mills are normally used to grind run-offmine ore or primary crusher product. Feed size to the mill is limited to that size which can be practically conveyed and introduced into the mill. The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a ball mill, pebble mill, or

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.
As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor. A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is
The ball mill noise control is to control the noise output of the ball mill in the process of crushing materials by the engineering measures and is also to control the spread and receive of the noise, which is in order to reach the required acoustical environment. ... Add an acoustic cover. ... the noise level will decrease at 9 dB (A) and the ...

Electronic Ear is useful for Control & Regulation of Ball Mills, using the grinding frequency signal for optimizing the Mill Output. It consists of an acoustic signal receiver (Microphone Unit / Sound Sensor) and specially constructed indicating & interpreting electronic circuit (Control Unit).
The results in SAG-Mill line 2 are even more dramatic. Because of segregation on the coarse feed stockpile, SAG-mill 2 receives a higher percentage of coarse material. The KnowledgeScape strategy's ability to maintain smooth and stable operation of the mill was more apparent when contrasted to the DCS control on the "difficult" line.
Therefore, it is possible to send information regarding the strain in the mill shell not only when the strain transducer is on the top and on the bottom of the mill, but also during the mill revolution. Mill charge in grinding ball mill circuits 1335 The signal from the receivers is sent to the control room.
