【摘要】：针对采用规定粒度计算筛分效率以评价多层概率筛工艺性能方法的局限性,提出分别采用规定粒度和分配粒度作为分级粒度计算筛分效率,进行多层概率筛工艺性能综合评价的方法。该方法利用最优法计算筛分物料产率,确定规定粒度和分配粒度,分别计算两种分级粒度下的筛分效率并进行比较。若两者相差较大,表明概率筛筛分性能没有得到最大程度的发挥,可通过调整筛分参数使得分配粒度和规定粒度尽可能接近,获取概率筛的最佳分级效果。最后,将此方法应用于中联重科机制砂概率筛2GLS2030工艺性能的评价,为产品后续改进提供了重要指导。
[Abstract]:In view of the limitation of the method of evaluating the process performance of multi-layer probability sieve by using the specified granularity calculation sieve efficiency, it is put forward that the specified granularity and the distribution granularity are respectively used to calculate the sieving efficiency of the multi-layer probability sieve. The comprehensive evaluation method of process performance of multilayer probabilistic sieve was carried out. The method uses the optimal method to calculate the sieve material yield, determines the granularity and the distribution granularity, calculates and compares the sieving efficiency under the two gradation granularities respectively. If the difference between the two is great, it shows that the performance of probabilistic sieve has not been maximized, and the best grading effect of probabilistic sieve can be obtained by adjusting the screening parameters to make the distribution granularity and specified granularity as close as possible. Finally, this method is applied to the evaluation of the process performance of the mechanism sand sieve 2GLS2030, which provides important guidance for the further improvement of the product.
