Abstract In the grinding process automatic control, detection and control of ball mill load is the important content of ball mill automatic control. Can detect the ball mill load accurately is a key to the success or failure of intelligent control of the whole ball. In the grinding sound signal measurements, the presence of the noise makes signal characteristics can not be extracted exactly

Noise monitoring for optimal mill operation Mining companies around the world continue to face the challenge of increasing productivity and reducing downtime. As part of its SAG mill control system, Manta Controls developed the Manta Mic a robust and reliable acoustic analyser that prevents mill damage.
Measurement System Of The Mill Charge In Grinding Ball. This is the reason for the unique stability of the quartz crystal strain transducer mill charge in grinding ball mill circuits 1333 the piezoelectric strain transducer the first application of piezoelectric strain transducers in 1982 involved force measurements on presses

I applaud Pueblo Viejo for this work. Sound control of a SAG mill is a subject that needs to be talked about more. I have been working on mill control, using microphones, for a good part of my career and I can say with much confidence that it works. Where I work now, Minera San Cristobal in Bolivia, we use sound control on both the SAG and Ball

Optimization of mill performance by using online ball and pulp measurements Soon after a stop, a mill is a dangerous place to enter for the personnel tasked with taking measurements or samples. Crash stops are difficult to handle. The mill and all feed streams should be stopped simultaneously but, often, they are stopped around about the same time.
A real time condition monitor system for the ball mill was constructed, which mainly consisted of an 34electric ear34 sensor, a set of sound card collection device and the LabVIEW8.0 software.
For a high energy loss and complex system of ball mill, this paper provide a ball mill load detection method based on genetic algorithm optimizing BP neural network. The effective frequency range of mill sound signal is analyzed. The soft measurement model of mill load based on mill sound signal is built. In order to solve the problem which converge slowly and easily reach minimal value, the
RETSCH is the world leading manufacturer of laboratory ball mills and offers the perfect product for each application. The High Energy Ball Mill E max and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time with only minor warming
The required sound level DB is entered manually as a set point into the Expert System, the sound of the mill charge motion is measured by 4 microphones adjacent to the SAG Mill shell, and the resulting signal is transmitted to the Expert system which, in turn, sends a set point to the SAG mill tonnage and speed controller.
controlled via a primary variable from a sound measuring system consisting of an array of microphones designed to measure noise and ball impact. However the microphone array based system was abandoned for the following reasons 1. The system was difficult to properly calibrate and remain tuned. 2.
The ball mills emit high pitch and low pitch sound depending on the material bed level in the grinding mill. Accurate measurement of filling levels and its communication in the form of a digital display helps utilize the ball mill more efficiently. Jayashree Electron has introduced a Ball Mill Operation Sensor series ESM428 to display and
