生球落下强度大小体现了固体颗粒间联接桥抗剪作用的强弱。
The drop number reflects the shear resistance property of liquid bridge between solid particles.
研究表明：随着粒度组成的细粒级部分的增多，生球落下强度呈上升趋势，生球爆裂温度呈下降趋势。
It has been shown that: as fine particle is increased in the raw material, drop number of green ball is increased and shock temperature is decreased.
结果表明，钠基膨润土能使生球落下强度、抗压强度显著提高；而钙基膨润土在改善球团爆裂温度方面优于钠基膨润土。
The results show that sodium bentonite can greatly improve the drop strength and compressive strength of green pellets, while calcium bentonite could enhance shock temperature of green pellets.
