The main machine of the flour milling equipment in the flour mill mainly peels the wheat by a pair of grinding rollers with speed difference and relative rotation, peels the wheat endosperm from the wheat skin, and grinds it into flour. The superior machine performance directly determines the quality of milling. The newly developed MMR type intelligent mill has innovative points such as front panel turnover, rotating cleaning of the feeding unit, integral disassembly of the grinding roller, automatic frequency conversion feeding, remote parameter setting and monitoring, and streamlined appearance of composite materials. It saves time and effort, catering to the world's low-carbon, green, and environmentally friendly manufacturing concepts, and has excellent performance in energy conservation, consumption reduction, sanitation, safety, and intelligent operation. Has four invention patents, one PCT international patent and four utility model patent technologies. The equipment is also used in other industries such as activated carbon, chemical industry, wine making and other industries to crush, crush and pulverize materials.
