环模和压辊是制粒机的核心部件，其结构参数对压制颗粒特性有直接的影响。为了提供合理的长径比确定依据，首先对制粒机进料高度进行分析，建立了进料高度数学模型；其次，对有效压缩区域面积进行分析，建立了有效压缩区域面积的数学模型；最后，依据有效压缩区域面积，建立了3种形式的环模、压辊结构参数和粉料密度、颗粒料密度间的映射关系模型。通过对这3种形式模型的对比分析，确定以环模压制颗粒1周为例得出的数学模型比较简洁，易于理解，适合在制粒机设计中进行应用。

Ring die and compression roller is the core component of granulator , and its structural parameters have direct effect on pellet feed characteristics .In order to provide the determining standard for reasonable length -diameter ratio , firstly , the mathematical model is established by the feeding height analysis of granulator .Secondly , through the analysis and calculation for the effective compression area , the corresponding mathematical model is also built .Finally , based on the area model , three types of mapping model between ring die structure parameters , compression roller structure parame-ters and density of powder and pellet feed are realized .In these three models , the one that the ring die makes pellet feed for one round is simple , easy to understand and suitable for application in the granulator design .
