tumbling mills where the particle size is reduced through a combination of impact and abrasion. The primary differences between these mills are in the ratio of diameter to the length of the cylinder and the type of grinding media employed. Grinding media can be steel rods, steel balls, hard pebbles or the ore itself. Autogenous and Semi ...
This type of mill is only suited for those kind of ores which are of a fairly coarse nature, but once they are broken, they readily disintegrate into smaller sizes. Typically, this type of mill can produce a product with a fineness of less than 0.1 mm. Testing of materials is needed beforehand for determining the suitability of the ore for processing in an autogenous mill.
