The aim of this study was to upgrade and improve the semi-automatic production process of kaolin grog. According to the production process, an automatic kaolin grog filling-packaging-unstacking cycle control system consisting of five steps was designed based on DCS control mode, including automatic conveying system of empty sagger, automatic filling system of raw kaolin, automatic robot palletizing system for kaolin packaging saggers, high-temperature sintering system for sagger piles, automatic robot unstacking system for product piles, and automatic recovery system for kaolin product. As a result, the full automation of kaolin production process was realized, and the direct exposure of workers to high temperature and dust environment was reduced. In conclusion, the automatic cycle control system was stable and reliable, and it reduced the labor intensity, improved the production efficiency.
