摘要
探究天然颗粒形貌对其破碎力的影响,对两河口的非规则灰岩颗粒进行平板压缩试验,用扁平度、细长度和不同类型的等效面描述颗粒形貌。试验结果表明:扁平度和细长度分布在一定范围内的非规则灰岩颗粒,其平板压缩破碎力与等效面积呈线性关系。根据线性关系最好的等效面,可以简单预估颗粒的平板压缩破碎力。
The irregular limestone particles from Lianghekou were investigated to explore the influence of shape of natural particles on its crushing force by the plates compression test.The flatness ratio,elongation ratio and equivalent areas were used to describe particle shapes.The experimental results showed that flatness ratio and elongation ratio distributed the irregular limestone particle in a certain range,whose breaking force and equivalent area show a linear relationship.The equivalent area of best linear relationship can simply predicted the plates compression crushing force of irregular limestone particles.
