Also, autogenous mills have grate discharges, so as to retain the coarse grinding media in the mill while dispatching the fine particles. The other benefits of using autogenous grinding include – reduction of metal wear, and elimination of secondary and tertiary crushing steps.
grinding mill,The mill power draw, throughput and product size distribution are used to compute a specific energy input and the MacPherson autogenous work index (AWI). Although the importance to achieve steady-state in a grinding test is widely accepted (Bond tests), the MacPherson test remains the only small-scale AGSAG mill test that offers this option.

the importance of autogenous grinding machine. Mineral processing typically involves the crushing and grinding of hard rock ore. Crushed ore is introduced to semi-autogenous grinding (SAG) mills, also known as primary mills, where grinding media is released like hammers to assist in the ore cracking / grinding process.
The Importance Of Grinding Autogenous Mill. Steady state is especially important in AG SAG mills where a harder component can build up over time and negatively affect operations Another advantage of this test is the generation of a seasoned charge This has particular value when considering autogenous circuits where the larger lumps must be present in the mill to provide …
