Research on Density of Two Kinds of Particles with Sharp Arris Form

LIU Yong-jie SUN Jie-jing SHEN Yuan-sheng (School of Materials Science and Engineering,Jinan University,Jinan 250022,China)  
The freeness packing density changes of disperse particles system with coarse and fine particles made by roundish wimble crusher were researched to discuss the character of dense packing structure of refractory products and to obtain the better particle packing density.The results showed that the freeness packing density was great when the diameter rate of coarse and fine particles was more than 5 and the mass fraction of coarse particles was 60%~70%.When the diameter rate of coarse and fine particles was less than 5 and there was not any fine particle,the changes of freeness packing density were smooth.
