Online Detection Of The Ball Mill Ball Filling Rate Study

Grinding was widely used in many departments, such as metallurgical industry, chemical industry, cement plant, ceramic industry, architectural industry, power plant and so on. Especially in the mineral processing department of metallurgical industry, it was more important. The control the process of grinding always was complex and difficult. So, those problems always attracted mineral processing engineers. The fill rate of the ball mill detection no had a online and available approach. Traditional methods had their own limitations and flaw. Manual testing the fill rate of the ball mill must waited until the mill stopped then opened the ball mill cover to enter to measure and calculate. This method was subjective and had a Great impact by human factors. Bad environment inside the ball mill. Temperature was 50℃or higher, it was very easily to lead to dizziness and other adverse reactions when people enter the ball mill. Seriously affected the accuracy of measurement. So, studied a accuracy, cost-effective and in the case of non-stop ball mill can be detection the medium filling rate of ball mill, which will be improving products quality and reduce the intensity of workers and cut down power consumption. It has important theoretical and practical value.The subject of this thesis was "Research for computer detection the filling rate of steel balls in Ball Mill". in the case of non-stop ball mill, stopped The supply of mineral, the same time the ball mill only received mineral cycle and water. After an appropriate period of time, inside the ball mill residual minerals have been discharged, Stay in the ball mill only was steel balls, linings, water and difficult to wear particles (This time the water and difficult to wear particles was a constant, The quantity of wear lining can be calculated according to the supplied parameters and formulas by manufacturer). Using the pressure sensors to examine the dynamic weight of the whole ball mill, After a series of data conversion module processing, eventually the data will be sent to the computer, and used a program developed by Kingview to achieve the filling rate of ball mill's online detection. In the experiments self-made device were carried out to achieved the design requirements.
