利用相似原理的模拟造型,是设计大型机械的最科学、最节约的方法.应用该方法关键要有清晰、准确的机械物理-数学模型.离心选矿机的选分机理迄今尚在研究中.因此,要找出它的完整、清晰的物理-数学模型还有一定困难.本文是根据目前对离心选矿机选分机理的认识,力图抓住其主要方面的物理模型.(一)离心选矿机选分物理模型矿浆在离心选矿机内的流动情况比较复杂.本文在分析离心选矿机的相似关系时,所 It is the most scientific and economical method to design a large machine using the analog modeling of similar principle, and the key to this method is to have a clear and accurate mechanical-physical-mathematical model.Selection mechanism of centrifugal concentrator is still under study so far , It is still difficult to find its complete and clear physical-mathematical model.This article is based on the current understanding of the classification mechanism of centrifugal concentrator, trying to seize the main aspects of the physical model. The physical model of slurry flow in the centrifugal concentrator is more complex.This paper analyzes the similarities of centrifugal concentrator, the
