doctrine of stratification on the basis of density difference in hindered settling rate
ganshe ehenjiang sudueha feneeng xueshuo干涉沉降速度差分层学说(doetrine of Strat-ifieation on the basis of differenee in hinderedsettling rate)美国人蒙罗(H.5.Monroe)为了解释跳汰选矿能够分选宽级别物料的事实，在1888年提出的一种动力分层学说，又称蒙罗分层学说，属于垂向分层理论。该学说认为粒群在有限空间内的沉降分层是按照各个颗粒的干涉沉降速度的大小自下而上排列的。蒙罗将颗粒的干涉沉降比作在窄管中降落。他取直径为d的颗粒，在直径为D的窄管中进行试验，得到干涉沉降速度公hs的计算式为 vhs一v。(1一几o·5)(1)式中v。为按牛顿公式计算的颗粒自由沉降末速;入为粒群的容积浓度，在此d/D一寻了。进入同一层次的不同密度颗粒可认为干涉沉降速度相等，即v、l一姗:，由此蒙罗得到干涉沉降等降比eks的计算式为 又，a，一刀11一又罕·5、2 ehs一寸.~不~-今{了一下几J.(2) 一稍d:占1一尸(i一又旦·“)式中al、a:分别为轻、重矿物的密度;p为介质密度。况一p/占，一p即是按牛顿公式计的自由沉降等降比。。由于在同一层次中轻矿物粒度dl总是大于重矿物粒度d:，故局部轻矿物的容积浓度久1也总要大于重矿物的容积浓度又2。结果由上式可见。hs>e。。当颗粒为球形，重矿物细颗粒充填在轻矿物粗颗粒间隙中，接近自然堆积状态时，蒙罗计算出最大的干涉沉降等降比。、一7.8e。，并以此解释了当粒群浓度增大后，在垂向介质流中可以分选宽级别原料的事实。 (不J‘玉波)
