摘要
20世纪80年代以来开发了大量的造粒粒度预测模型,其中最普遍的是质量集合平衡模型和数群集合平衡模型。数群集合平衡模型的研究比较完善,现已应用于工业。数群集合平衡模型建立在二元聚合机理基础上,是根据造粒过程中造粒总数量相等的原理建立模型。该模型可为研究连续操作的圆筒造球机的工作特性提供参考依据。介绍数群集合平衡模型的公式推导及该模型的意义。
A great number of mathematical models to predict granule size distribution have been developed since 1980＇. Most models belong to equality population balance （EPB） model and numerical population balance （NPB） model. NPB model is relatively perfect and has been applied in industrial production. NPB model is one of the fundamental models which regard to the mathematic model of the particle size prediction and is established on the basis of the mechanism of binary polymerization according to the total number equality to establish the balance equation during the granulation. This model can provide references for the performance characteristics of continuous drum pelletizer. The formula derivation of the numerical population balance model and its meaning are described in this paper.
