Although it is well known and easily experienced that the feed size distribution influences the throughput and stability of operation of a semi-autogenous grinding (SAG) mill, the details are poorly understood since it is often only the input and output measurements that are used to identify unfavourable in-mill conditions. Load cells and power monitoring are sometimes used …

Grinding mills in which comminution takes place without grinding aids are known as autogenous grinding (AG) mills or fully autogenous grinding (FAG) mills. These mills use large lumps of rock as the grinding media. Mills that use intermediate size rock or pebbles as a grinding medium are also autogenous mills but are known as pebble mills.

Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and 1.8:1. For fine regrinding in open circuit, the ratio ranges from 1.3:1 to 1.5:1. Some ball mills are separated in to compartments by grates.

Autogenous grinding is at present carried out in tumbling mills of the same types as used in ball mill grinding. The similarities in equipment and procedure have led to the commonly held assumption that the grinding mechanisms are the same in the two processes, with the coarse part of the ore charge taking over the function of the ball charge.

This permits adjusting for changes in the quality of the media. Secondary autogenous mills are low level diaphragm grate discharge mills with the length being one to two times the diameter. The low level discharge is required to obtain flow through the mill and maintain a pulp that will not float the charge.

Autogenous mills are also known as AG mills which is an acronym for autogenous grinding mills. It is so-called due to the self-grinding of raw materials inside the grinding chamber: a rotating drum throws large-sized raw materials in a cascading motion which causes impact breakage of larger particles and compressive grinding of finer particles.
