Title Green ring die pellet’s 3D design andperformance analysisAbstractPellet mill is one of the four main machines in feed industry. Ring diepellet mill is one of the most widely used machines and has an effect onthe production and quality of feed processing. At the beginning of 1970,thering die pellet mill was introduced to China, and China started designingand manufacturing ring die pellet mill. However, until today, the pelletmills that designed by China still have many problems, such an lowproduction, high power cost and so on, which seriously hampered thedevelopment of Chinese feed industry. Therefore, analysis of the structureand the performance of pellet mill is very necessary. This paper is mainlyfocused on the structure design. The major jobs are as follows:Firstly, Read the relevant literature to learn the current situationand the structure of ring die pellet mill at home and abroad.Secondly, complete a design of a green ring die pellet mill, includingthe design of main transmission，feed conditioner, die and roll and theconnections between them. And then, And draw its 3D structure andengineering drawings, complete the assembly.Thirdly, do the performance analysis and strength check of thesimplified model.
