Actual production the media movement theory to determine the milling machine suitable working speed is 76% and 88% of the critical speed, turn rate of the majority of our current manufacturing ball mill in the range of 75% to 80%. Mill appropriate speed but also through temporary production comparison test to determine. Comparison, not just look at the level of the mill production capacity, but also the power consumption of steel consumption and economic benefits. A mineral processing plant in the country for eleven series 3200mm 3100mm ball mill speed the temporary industrial scale comparative test results the filling rate remains 44% to 48% under the conditions, and the ball mill speed 18r/min speed rate of 74.3% to 19.8r/min speed was 81.72%, the whole plant is an annual processing ore increased by 45,800 t annual electricity consumption increased 6.574 million kw h liner consume 388.48t raising the cost of $ 0.38 per tonne of concentrate, lead to the whole plant throughout the year ball mill speed is increased and a profit of 567,900 yuan less. That is, increasing production without increasing income, the conclusion is negative. Depends on the rotational speed of the mill grinding media in the state of motion of the cylinder body. The state of motion of the medium, when other conditions remain unchanged. Grinding effect is not the same. Mill speed is low, the medium to diarrhea mainly fall sports, the impact is less grinding role mainly lower grinding mill production capacity, suitable for fine grinding media Paola movement; higher speeds, way proportion increases, the role of a strong impact grinding role to impact, grinding stripping Secondly, there is help crush the coarse-grained materials, the production capacity of the mill. The mill filling rate, the useful power reaches a maximum when the required speed is not the same. Filling the higher the rate, in order to ensure the innermost ball in Paola movement requirements of the mill, the higher the speed, the caliber of the useful power reached the maximum, so that the mill has the greatest productivity.
