摘　　要：为研制小型饲料制粒机,进而促进饲料及其有关产品的个性化、多样化、精细化生产和研究,分析了环模制粒机制粒成型过程与工作原理;并以小型制粒机为研究对象,结合物料的摩擦特性与环模结构尺寸,分析了不同攫取角度、不同压辊结构参数、不同模径辊径比与挤压物料高度、生产率的关系;确定了小型制粒机压辊的主要参数。理论分析和结构设计对小型制粒机的研制及改进具有重要的指导意义。In order to develop small-scale pellet mill,thus contributing to individualized,diversified and refined production and research on feed and its related products,pelletizing process and working principle on pellet mill were analyzed.Focused on small-scale pellet mill,and combined with friction characteristics of material and structure size of ring die,the relationship between the main parameter(such as different grabbing angles,different roll structure parameters and different die-roll diameter ra tio)and extrusion material height with productivity were analyzed.Finally,the main parameters of small-scale pellet mill are identified.Theoretical analysis and structural design in this paper have an important guiding function on development and improvement for small-scale pellet mill.
