采用分级效率指标来评价物料按粒度进行分级过程的效果,是比较简便易行的方法。在实际计算中,正确地选择和使用分级效率的计算公式是常不被人们注意的,往往采取套用的方法。
The use of grading efficiency indicators to assess the effect of grading process based on the particle size is relatively simple and easy way. In the actual calculation, the formula for selecting and using the classification efficiency is often not noticed, and often applied.
