| 摘 要： | 采用一种简单的筛分装料法测定粉料松堆积密度，并利用电动跳桌实现其紧密堆积，经试验证明，该法装料均匀，测定结果重复性好，利用测定结果，能够正确估计粉料颗粒的相互作用力大小，颗粒级配、颗粒凝聚等粉料特性。

| Abstract: | A simple filing method by sieving was developed to measure bulk density of pow-der. And the powder is packed with the aid of electric jump-table for packed bulk density. Itis shown that this sieving method can fill the powder well-distributedly and the results arewell repeatable. Some characteristics of powder, such as interaction force between particles,grade or coagulation of particles etc. , can be estimated correctly based on the results of mea-surement. |
