Abstract: Since the 1970s, the semi-automatic grinding process has been diversified, from the initial single-stage semi-automatic grinding process to the semi-automatic grinding + ball milling (SAB) process and then to the semi-automatic grinding + ball milling + stone crushing (SABC) process. Compared with the traditional crushing and grinding process, the semi-automatic grinding process has the advantages of low energy consumption, small footprint and simple process, and it improves the efficiency of the semi-automatic mill and increases the processing capacity of the semi-automatic mill. This article summarizes the application of semi-automatic grinding technology at home and abroad in recent years, and puts forward several suggestions for the future development of semi-automatic grinding technology.
