为探讨作者计算多组分粒度体系填充体积的方法，讨论了耐火材料配合料粒度级配模型的各种方程，并推导了新的模型。采用作者的计算方法，计算了镁熟料混合料棒贯成型填充体的体积和镁熟料混合料压制成型填充体的体积。结果表明：最密堆积的颗粒尺寸分布与观测趋势吻合较好，但填充体积的计算值与观测值不一致。然而，发现通过将值作为组分数量和最细粒度组分的数量或级配系统系数的函数进行修正，可以达到一致。并讨论了适合耐火材料配合料的级配模型。
To survey the author's method for calculating the packed volume of multi-component particle-size systems, the various equations for particle-size grading model for refractory batches were discussed and new model were derived.Employing the author's calculating method, the volumes of bodies packed by moulding method with stick penetration of magnesia clinker mixes, and the volume of bodies packed by press moulding of magnesia clinker mixes, were calculated.From the results, it was shown that the particle-size compositions or particle-size distributions of closest packing were in good agreement with tendency for those of observations, but the calculated values of packed volume were not agreed with observations.It was found that, however, the agreement could be achieved by the modification with values as function of number of components and the amount of finest-size component or grading systems coefficient.And the suitable grading model for refractory batches were discussed.
