Abstract Batch grinding kinetics with assumptions is applied to continuous tube milling to describe the grinding performance, relating the degree of size reduction to the milling conditions including the scale-up variables. As to the scale-up effect on the degree of size reduction, the trend predicted is confirmed with that observed in industrial cement mills in reasonable agreement. The equation of the grinding performance alone, however, does not evaluate the mill diameter and the length individually nor guarantee the powder filling to be a desired level. Then, it is proposed to use one more equation representing the material hold-up (or the powder filling) in relation to the milling conditions. That is, the solution of the two simultaneous equations enables the two variables (the mill diameter and the length) to be evaluated, satisfying the powder filling to be a desired value.

水泥行业连续管磨机的放大和设计基础

摘要 带假设的批量磨削动力学被应用于连续管磨以描述磨削性能，将尺寸减小程度与包括放大变量在内的磨削条件联系起来。至于对尺寸减小程度的放大效应，预测的趋势与在工业水泥磨机中观察到的趋势相吻合。然而，单独的研磨性能方程并不能单独评估磨机直径和长度，也不能保证粉末填充达到所需的水平。然后，建议使用另一个方程来表示与研磨条件相关的材料滞留量（或粉末填充量）。也就是说，两个联立方程的解可以评估两个变量（轧机直径和长度），
