Deflocculation state was considered to be necessary for better fluidity and spreadability of barium sulfate suspension taken as an X-ray contrast medium in the examination of gastro-intestinal tract. The Zeta-potential of the barium sulfate particles in increasing. concentration of different electrolytes was measured by the eletrophoretic method in a Burton Cell. The results were compared with the corresponding sedimentation volume. It was found that the Zeta-potential ranging from 50 mV to 66 mV favored the deflocculation of the suspension, while that below 22 mV, flocculation was affected. The viscosities of 100%, 130% and 150% barium sulfate suspensions were measured using Hoppler's Rheo-viscometer. The viscosity dropped quickly at first on the addition of electrolytes, and then increased to some extent with further increase of electrolyte concentration. The minimum viscosity was considered to reflect complete deflocculation of the suspending particles. The electrolyte concentration producing minimum viscosity was shown to be the most effective deflocculating agent tested, while sodium pyrophosphate and sodium citrate are less effective.The flocculation of the barium suspension by the gastric fluid after ingestion often leads to some troubles to the roentgenologists. We examined the ability of different electrolytes to retard such flocculation by means of the viscosity method.

测定了硫酸钡不同工艺制成品的粒度分布。证明北京三厂中间产品(湿膏)本来粒度很细有97%是在4μm以下,但烘干后成品粒度变粗,80μm以上的粒子占62%。这对造影效果会产生重要影响。喷雾干燥产品的粒度分布与原湿膏基本相同。用电泳法测定了硫酸钡混悬剂的动电位,确定硫酸钡是荷负电的。混悬剂的动电位在22mv以下可产生絮凝,适合于反絮凝的动电位是在50~66mv之间。电解质中六偏磷酸钠、焦磷酸钠和柠檬酸钠的反絮凝效力是按上列顺序减低的。例如配制100%硫酸钡混悬液三种电解质最适宜的浓度分别为5×10~(-3)M、2×10~(-2)M和3×10~(-2)M。本文用粘度分析法研究了混悬液的絮凝反絮凝过程,所得结果与动电位和沉降容积的结果基本吻合,惟粘度法方便迅速并能反映出细小的变化,可用数字和曲线作鲜明的对比。但此法要求颗粒要细(10μm以下)否则会发生机械性阻碍无法测定。

According to the matrix theory of comminution, which involves the concepts of the classification matrix and breakage matrix, the mathematical models of roll crushers and rotary breakers of coal preparation plants have been investigated in this paper.For the roll crusher model, the classification matrix is expressed by a certain equation. The breakage matrix is developed firstly by a single particle pendulum breakage test, and then by a computing calculation for the test data using a multidimensional cubic spline regression technique.The rotary breakage involves three subprocesses:prescreening, crushing and, rescreening. The prescreening and rescreening suoprocesses are represented by a simple efficiency curve model. Modelling the crushing subprocess uses the same concept as the roll crusher model, but needs more assumptions. The feed of the rotary breaker is considered to be divided into two components( "coal" and "ash"). These two components have the same classification function but different breakage function. They are also selected for breakage at different rates. The crushing and rescreening subprocesses repeat for several stages.The above two models have been tested using a number of industrial experimental data. It has been found that they can be used to predict the size distribution of crushing products with reasonable accuracy.In addition, an empirical model has been developed to predict the ash content ot the broken coal fractions.

根据粉碎(作用)的矩阵理论(包括分级矩阵和破碎矩阵),本文提出了选煤厂辊式破碎机和选择性破碎机的数学模型。在辊式破碎机的模型中,分级矩阵用一个方程式来表示。破碎矩阵的导出,需先进行单颗粒煤样的摆锤破碎试验,然后用多维三次样条回归技术作计算机处理。选择性破碎机的整个过程由三个子过程组成:预先筛分,破碎和检查筛分。其中,预先和检查筛分的模型用一个简单的效率曲线公式来代表。破碎子过程的模型与辊式破碎机模型的概念类似,但需作进一步的假设:选择性破碎机的入料是纯煤和纯灰的混合物;这两种成分的分级函数相同;它们的破碎函数不同,且进入破碎子过程的选择率也不同;破碎和检查筛分两个子过程是多段反复进行的。经检验,上述两个模型可用朱比较准确地预测破碎产品的粒度分布。此外,本文还提出了一个预测破碎产品各粒级灰分的经验公式。
