15/04/2019· There are many factors affect the grinding efficiency of ball mill. Many factors can be judged as qualitative analysis, which are difficult to make quantitative analysis. Therefore, the ball mill operator must do a comprehensive analysis according to the actual production situation and the result of the qualitative analysis, thus drawing the reasonable parameters to decrease

Effectively improving the grinding efficiency of the ball mill can increase the output and improve the efficiency of the concentrator. After the long-term operation, most concentrators will encounter the problem of reduced grinding efficiency of ball mills, which affects the normal operation of the entire concentrator. Following are some methods for improving the grinding

18/03/2021· The grinding effect of the ball mill directly affects the grinding efficiency and the output of the ball mill. In addition to considering the size of the ball mill, internal structure of the ball mill, product fineness requirements and other factors, should also consider the characteristics of the grinding material, such as grindability, particle size, etc.

Addition of pebbles to a ball-mill to improve grinding efficiency . Ball-mills are used widely for secondary grinding. Loveday (2010) reported on laboratory tests in which small pebbles (7–25 mm) were used in various improving the grinding performance in ball mills with a - ORBi. Observations have been done without the use of the Sensomag, suggest- ing a better

26/12/2017· According to Bond (1954), the grinding efficiency of a mill depends on the ball mill diameter, size of the media and mill speed. Ball mills with different length to diameter ratios for a particular power rating will produce different material retention times. The longer units are used for high retention ratios while shorter units are used where overgrinding is a factor to be

26/10/2020· 2.More crushing and less grinding, reducing the feeding particle size of ball mill. The larger feeding particle size is, the greater the work done by the ball mill on the ore, which impacts the grinding efficiency. To reach the eligible grinding fineness, the workload must increase. The energy consumption is also increasing.
