The gold grinding machine, also known as a wet mill or wet grinding machine, can be categorized based on its working method into gold grinding machines, mercury mixing mills, iron grinding machines, and electric mills. Based on the structural design, it is divided into wheel mills, double-roll mills, and three-roll mills. It is mainly used for the grinding, beneficiation, and processing of ores such as gold, silver, lead, zinc, iron, molybdenum, copper, antimony, and rare and precious metals like gold and silver. Any ore that can be processed by a ball mill can also be processed by a wet grinding machine. It is easy to install and maintain, has low investment, high output, fast results, and low production costs, making it an ideal device for beneficiation in small and medium-sized enterprises in mining areas.
