ABSTRACT
Pellet mill is one of the agricultural machinery, which plays an important role in the feed processing machinery, and it’s widely used in feed processing industry. Though the domestic feed processing machinery enterprises have made great progress in the machine design，manufacture，and improved the appearance and performance of the products，compared with the same foreign equipment，domestic pellet mills still have a lot of disadvantages such as unreasonable structures，low productivities，high energy consumption．These have restricted the international competitiveness of the domestic pellet mill．
This paper is mainly focus on the ring-type matrix of pellet mill. The process and the fundamental principle of pellet mill are introduced, including the classification and the development of pellet mill. Meanwhile, three-dimensional model are created. Then we can analyze the performance of the ring-type matrix all by the computer.
At last, in order to optimize the pellet mill, we make a test and finite element analysis on the ring-type matrix.
Keywords: ring-type matrix, pellet mill, finite element
