Autogenous grinding is a process of grinding ore in a rotating cylinder, using large pieces of the same ore. Autogenous mills operate mechanically like ball mills; however, the media used for grinding differs. Simply put, in autogenous grinding, the media is also the material that is being ground, whereas in other milling methods steel or ...

Bavarder sur InternetIn autogenous grinding, a distinction is made between ore and ore-pebble grinding. Ore grinding is carried out in mills with a large diameter (up to 12 m) and short length (the ratio of diameter to length is approximately 3). Ore with pieces having dimensions up to 300 mm (sometimes, up to 600 mm) is loaded into the mill.

The term autogenous grinding came about due to the concept of self-grinding of the ore. It is also referred to as "Run of Mine" or ROM grinding. A sturdy, rotating drum throws larger rocks of ore in a cascading motion, causing impact breakage of similar smaller rocks that need to be ground into finer particles.
