摘　　要：利用三种铁矿石物料的窄粒级颗粒床压载粉碎试验结果验证先前建立的一种关于粒间粉碎的物料模型对这些矿石物料的适用性,并且利用这三种物料的宽粒级颗粒床压载粉碎试验结果进行该物料模型的参数求解研究。结果表明,实验室颗粒床压载粉碎试验与数学建模方法相结合是研究和优化矿石物料粒间粉碎的一种有效方法。Using the results of comminution tests by compressive stressing particle-bed with narrow size fractions of 3 kinds of iron ore, the suitability of a previously-developed material-characterization model for interparticle breakage is verified. And further the methodology for determining the material parameters of this model based on test results of compressive stressing of particle-bed with wide particle-size distribution is investigated. It is shown that the laboratory particle-bed compressive comminution test combined with mathematical modeling technique provides an effective way to study and optimize the size-reduction of ore material by interparticle breakage.
