摘要(Abstract)：

本文以湖南柿竹园公司钨矿石为研究对象，计算其实验室批次瓷球和钢球磨矿产品动力学模型，与钢球进行比较并验证该预测模型的准确性。试验结果表明，瓷球磨矿与钢球磨矿相比，粒度较大颗粒（+0.15 mm）破碎速率明显低于钢球，对粗粒级钨矿石的破碎具有局限性；细粒级的零阶产出特征结果表明，瓷球磨矿已经改变了钨矿石碎裂特征，a值较钢球磨矿降低0.15，其破碎主要作用力由法向冲击力改为切向研磨力，可以有效避免贯穿破碎，降低次生细泥生成；钨矿石瓷球磨矿动力学特征趋向于一阶磨矿动力学模型，其模型方程式为R=R_0e~(-(0.027+11.85d~(1.93)))t分布，试验结果说明该模型对钨矿石的动力学模拟较为准确，可以用来预测各磨矿时间下磨矿产品的粒度特性。

关键词(KeyWords)： 钨矿石;磨矿动力学;零阶产出特征;碎裂特征
