| 摘 要： | 以本钢歪头山铁矿石为试验物料,采用JK落重试验和Bond球磨功指数试验研究了矿石的碎磨特性参数。结果表明:冲击粉碎参数A为65.53,b为1.06,A×b为69.46;磨蚀粉碎试验获得的矿石磨蚀系数t_a为0.72;相对密度测定试验获得的矿石相对密度为3.31。Bond球磨功指数试验获得的球磨功指数Wib为7.64 kWh/t,碎磨特性参数和Bond球磨功指数表明,歪头山矿石属于软矿石范畴,其抗冲击破碎能力和抗磨蚀能力都比较弱,矿石中没有难磨粒子。

| Abstract: | The Waitoushan ores were used as the experimental material.The comminution parameters are obtained by using JK Drop Weight Test and Bond ball mill index test.The results show that the impact comminution parameters A=65.53，b=1.06，A×b=69.46，the abrasion comminution parameter ta of the abrasion crushing test is 0.72.The relative density of ores obtained by relative density measurement is 3.31.Bond ball mill work index is 7.64 kWh/t by corresponding Bond ball mill work index test.The results of Comminution parameters and Bond ball mill work index indicate that Waitoushan ores belong to the category of soft ores，both its impact crushing resistance and abrasion resistance are weak，there are no hard grinding particles in the ores. |
