[0003] The full name of wet mill is wet grinding mill. According to different operation modes, it can be divided into gold mill, mercury mill, iron mill and electric mill; according to different structural modes, it can be divided into wheel mill, double roller mill and triple roller mill. Wet mill is developed through modern improvement on the basis of ancient stone mill. It is used for grinding of various ferrous metals, non-ferrous metals and non-metallic minerals, as well as grinding, selecting and processing of rare and precious metals such as gold and silver. It is the best grinding equipment for medium and small ore dressing plants and milling plants.

[0004] In the processing of dead-burned magnesia, a wet mill is required to crush the raw materials.
