Granulation molding equipment is the most critical link in the granule feed production line. The ring mold granulator is one of the main equipment of feed machinery, but its low life, frequent failures, and high maintenance costs seriously restrict the development of granulators in China. Based on the minimum maintenance model, this paper proposes the timing replacement strategy (CIRP) analysis, so as to obtain the Weibull probability diagram of the time between failures and obtain the fault distribution mode, fault frequency, and reliability of the sub-system of the ring mold granulator. By analyzing the failure statistics of the ring mold granulator, it is concluded that the granulator system and transmission system are the main causes of failures. Improvement measures are proposed for the weak links of the ring mold granulator, providing an important reference for improving the life of the ring mold granulator and reducing failures.
