在比较了各种常数n和雷诺数的基础上,提出了适合于粗煤泥分选的预测数学模型。使用实验室自制干扰床分选机系统,对0.3~2 mm粒级粗煤泥进行了分选试验,通过比较试验值与模型预测值,验证了模型的准确性。结果表明:K-R模型和R模型可以用来预测干扰床的分选性能。 Based on the comparison of various constants n and Reynolds numbers, a mathematical model suitable for coarse slime separation was proposed. The laboratory self-made interference bed sorter system was used to separate 0.3 ~ 2 mm coarse coal slime. The accuracy of the model was verified by comparing the experimental values ​​with the predicted ones. The results show that K-R model and R model can be used to predict the performance of the disturbed bed.
