摘要在这次设计过程中，根据颗粒机总体设计要求设计零部件，对零部件的尺寸、材料、零部件之间的配合进行分析、计算、选择。并对重要的零部件或者要求高的零部件进行有限元分析设计。选用尺寸尽量避免零部件之间的干涉问题，尺寸合理。70010

本次设计是在导师董广强教授的大力支持下。在董教授的耐心辅导下我与胡伟同学合作，共同设计出一套致力于生产木屑颗粒与饲料颗粒的机械装备。此装备利用环形制粒模，利用压辊从径向滚压挤出模型长条，切刀片将长条切成颗粒。就是本次设计的原理基础，

设计一种颗粒机，将秸秆等材料进行粉碎，并挤压成所需颗粒，实现秸秆深加工利用。本次设，我根据颗粒机总体设计设计零部件，对零部件的尺寸、材料、零部件之间的配合进行分析、计算、选择。并对重要的零部件或者要求高的零部件进行有限元分析设计。选用尺寸尽量避免零部件之间的干涉问题，尺寸合理。

Particle machine parts design

Abstract During the design process, according to the general design requirements of the design particle machine parts to fit between the parts dimensions, materials, parts and components analysis, calculation, select. Finite element analysis and design of important parts or demanding parts. Size selection to avoid interference problems between components, reasonable size.

This design is the strong support of Professor under the Offset. I worked with the students in Professor Hu Wei Dong patient counseling, to design a set dedicated to the production of wood pellets and feed pellets machinery and equipment. This granulation ring mold equipment use, the use of model roll out radially from the strip rolling, cutting blade strips cut into pellets. This principle is the basis of design, design transmission mechanism, feeding mechanism, forced feeding mechanism, and a variety of component design, design a set of particle machine equipment.

Design under the guidance of Professor Dong Now a lot of domestic and foreign about this set of equipment related to the literature data, through the existing theory and related mechanical analogy, based on this set of particles to be designed machine equipment.

Key words:  Granulating mould   Granulating machine finite element analysis
