Factors Influencing the Optimization of Autogenous Grinding Mills
The mill was fed from two different bin systems through balances and conveyor belts. The feed rate was calculated from flowrate and percent solids of weight. Energy consumption per ton of feed was calculated from the total energy consumption of each test. Particle size distribution was determined by conventional screening to -44µm …
Autogenous Grinding
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 ...
