【摘要】 通过物料的受力分析确定了物料攫取条件，并分析了物料层厚度ｈ０ 与攫取角β、模辊径比λ之间的关系，从理论上解释了颗粒机生产率随模辊径比λ和攫取角β、压辊数目Ｚ变化的规律，从而简化部件的研制过程，为正确设计颗粒机提供了科学根据更多还原

【Abstract】 By the force analysis, it defines the conditions to seize the material, and analyzes the relation between the layer thickness of the material h 0 and the seize angle β and the diameter ratio of mould to roll λ as well, It explains the rule of the pellet machines productivity changing with the diameter ratio of mould to roll λ, the seize angle β and the amount of press rolls Z theoretically and thus it simplifies the research process of parts, it also provides scientific bases for designing pellet machine correctly.更多还原
