摘要
在对选煤分配曲线形态研究的基础上,运用数理统计方法进行推导,建立了重力选煤分配曲线的偏正态模型.经检验,所建立的模型较标准正态模型预测重力选煤的分选效果精度高。
On the basis of the form research of distribution curve for separation, using the method of mathematical statistics establishes quensinormal model of distribution curve for heavy-media separation. Examination confirmed the model estabilished is more accurate than standard normal model in forecasting separation performance.
