Autogenous Grinding Article about Autogenous Grinding

In 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. If only a small amount of the large fraction is present in the ore ...

Autogenous Grinding - Mining Fundamentals

Autogenous grinding is gaining in popularity, as the grinding media costs are much less, and this process does not produce as much slime or fines as traditional rod and ball mills. Autogenous mills can handle both wet and dry operations. In some applications that require the grinding of minerals, such as talc, asbestos, and mica, dry semi-autogenous milling is the preferred choice. Grinding is ...
