采用多因素试验和计算机多元回归技术,分析了能耗与产品粒度或能耗与粒度比表面积之间的关系,确定了新的能耗-粒度模型,揭示了球磨机产品粒度对能耗的高度依赖性.同时验证了提高分级效率对降低能耗的重要性,并且提出了在兼顾粒度与能耗的前提下使用超临界转速(约120%C.S.)以获得较细产品粒度的可能性
The relationship between energy consumption and product particle size or energy consumption and particle size specific surface area was analyzed by multivariate test and computer multiple regression analysis. A new energy consumption - particle size model was determined, which revealed that the ball mill product size is highly dependent on energy consumption At the same time, the importance of increasing the classification efficiency to reduce energy consumption was also demonstrated, and the possibility of using a supercritical rotation speed (about 120% CS) to achieve a finer product particle size with both particle size and energy consumption put forward
