Ball mills can be divided into two types based on dry and wet conditions. Generally, dry ball mills are suitable for metallic and non-metallic ores, including materials that react with water, such as cement, marble, and other building stones, or products that require storage and sales in powder form. In addition, if the selection plant is located in arid areas with limited water resources, dry ball mills can be used for water conservation considerations. Wet ball mills have a wide range of applications and can handle metal and non-metal ores, including common ones such as gold, silver, copper, iron, molybdenum, phosphate, feldspar, fluorite, and so on. As long as it is ensured that the contact of materials with water will not affect product quality, a wet ball mill can be used. Ores that require sorting treatment are usually treated using a wet ball mill. According to different mining methods, it can be divided into two types: grid type and overflow type.

Working in mineral processing plants in areas with poor water sources, mineral processing plants that avoid water, and minerals with high viscosity after discharge are all suitable for using dry ball mills for grinding. In other cases, using wet ball mills for grinding has a stronger practical effect and is more environmentally friendly and energy-saving. For raw materials with unique chemical changes, ceramic ball mills can be selected, and their lining plates are made of porcelain, with smoother characteristics.

Dry ball mills cannot perform wet grinding, they can only be ground in dry natural environments. In terms of design, the feeding point of the dry ball mill is in a straight cylindrical shape and equipped with equipment such as fans, dust removal pipes, and dust removal equipment. The cross wet ball mill has a complex structure for dry testing.
