Abstract
The design of autogeneous grinding mills is difficult because of the
variability of their grinding media; when steel balls or rods are used
as in SAG or non-autogenous machines, calculations can be much more
reliable because--obviously--the characteristics of the media are
constant, or predictable. But when the grinding medium and the feed
material are one and the same thing, the variations in the physical
characteristics of the feed multiply the design problems, especially in
the case of autogenous primary mills. Now, however, researchers from
Outokumpu, Finland, working backwards after years of studying full scale
autogenous production mills, are developing a special laboratory method
to test the suitability of ores for Outogenius comminution, Outokumpu's
own autogenous grinding process. This paper discusses the results of
these new grinding machines which use ores to grind ores. The
specifications of the machinery are provided along with the performance
on various types of ores.
