autogenous grinding benefits

Autogenous Grinding - Mining Fundamentals
Grinding is easily enabled in autogenous mills by attrition. 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.

What is Autogenous Grinding?
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. The other benefits of using autogenous grinding include – reduction of metal wear, and elimination of secondary and tertiary crushing steps.
