semiautogenous and autogenous mills
A Method of C alculating Autogenous/ Semi-Autogenous
· Rod mills are limited in size to 2000 kW because the longest commercial grinding rod available is 6 m long. For this reason rod mills are rarely selected in the present day environment of large AG/SAG mills and large ball mills. However it is necessary to discuss their operation because a Rod mill product has a similar slope to AG/SAG mills.

Semiautogenous mill Britannica
In mineral processing Grinding development is the autogenous or semiautogenous mill. Autogenous mills operate without grinding bodies instead the coarser part of the ore simply grinds itself and the smaller fractions. To semiautogenous mills (which have become widespread) 5 to 10 percent grinding bodies (usually metal spheres) are added.

Characterization and Modeling of Semi-Autogenous
Abstract Advance control of semiautogenous (SAG) grinding has become a major issue for mining companies. SAG mills are very complex systems involving important nonlinearities and unmeasured disturbances which make the process very difficult to control. In the last decades approaches varying from decentralized PID control to multivariable predictive control have been applied to control of SAG
