邦德冲击破碎功指数
Bond work index of impact crushibility
bongde ChongJJ Posujgong zh一shu邦德冲击破碎功指数(Bond work index ofimpaet erushibility)表征矿石可碎性的指标。该指数通过测定物料破碎时的能耗，反映物料可碎性。是美国邦德(F.C.Bond)于20世纪50年代提出的。 采用双摆锤冲击试验机，即低能冲击试验机(图l)进行测定。通常称为低能冲击破碎功指数。测定方法缨 图1低能冲击试验机是使被测物料两侧受到相同的冲击功。锤头质量m为13.6Ikg，摆锤长度L为711.Zmm，摆锤打击面为somm只somm。测定时取20块拉度为一75~+somm的物料，放置在砧座上，摆锤以5a的提升角度梯度逐渐升高，然后释放，直至击碎物料为止。用 Wi一2 .59KC/s，计算，式中Wic称为低能冲击破碎功指数;K为因次换算系数;C为单位试件厚度的冲击破碎功(称为可碎性系数)，c一KIK:(l一 cos争)/S，式中K:为仪器系数，K:为换算系数，小为摆锤最大摆角(物料破碎时的摆角)，s为试件厚度;S:为试料真密度。 1982年美国艾里斯一卡尔默斯(Allss一ehalmers)公司研制成功使用高能冲击试验机(图2)的高能冲击功指数测定技术。它与低能冲击试验不同之处是设置了冲击摆和回弹摆，用回弹摆吸收物料破碎后的多余能量，因此，一次高能冲击即可使物料破碎。高能冲击破碎功指数W，的计算公式为ha 图2高能冲击试验机 1一主冲击锤;2一主滑杆;3一回摆锤; 4一从动滑杆，5一刻度器;6一密封箱; 7一吊索;8一底架;9一上架 10 10 w:一W/(惹一惹’式中W为单位破碎能量;FS。为原料中80%通过的粒度;尸8。为产品中80%通过的粒度。被测定的原料粒度为20一somm。 低能冲击破碎功指数适用于计算物料粗碎的破碎能耗;高能冲击破碎功指数适用于计算物料中碎和细碎的能耗。 (王宏勋)
