在均质和非均质两个大标题下讨论了不同类型矿浆的行为,讨论了以小管径获得的压差数据比例放大到大直径管的方法,推荐了用于不同矿浆的最佳方法。推荐鲍恩(Bowen)法用于以均质方式流动的矿浆。对非均质流动矿浆则证明了它们在小管子内的行为如何可被进一步划分为半非均质或完全非均质行为,对后者的比例放大方法推荐了杜兰德(Durand)方程式,对往往最有工业价值的前者,证明了为什么还没有能充分描述它们行为的关联式,并为这些矿浆推荐了一个新的比例放大公式。所有的比例放大方法均用得自50～300毫米直径管的试验数据来说明,证明了在不大干100毫米直径管内的试验如何可在比这大三倍直径的管内精确地预测压差到15％以下的误差。
The behavior of different types of slurries is discussed under both the headings Homogeneous and Heterogeneous, and the method of scaling the pressure difference data obtained with small diameters to large diameter tubes is discussed. The best method for different slurries is recommended . The Bowen method is recommended for use in slurries that flow in a homogeneous manner. For heterogeneous mobile slurries, it turns out how their behavior in small tubes can be further divided into semi-heterogeneous or fully heterogeneous behavior. The Durand equation is recommended for the latter method of scaling up, The former with the highest industrial value proves why there is no correlation that adequately describes their behavior and suggests a new scaling formula for these slurries. All scaling methods are illustrated by experimental data obtained from 50 to 300 mm diameter tubes demonstrating how a test in a small 100 mm diameter tube can accurately predict the pressure differential in a tube three times larger than this Less than 15% error.
