Autogenous Grinding 911 Metallurgist

2019-12-17  Secondary Autogenous Grinding — Pebble Milling In the early summer of 1961, Dr. Jackson wrote a second paper on the South African milling practice for gold and uranium ores. This paper gives the details on several forms of autogenous grinding. Nearly all of the secondary and tertiary comminution is done in pebble mills in this country.

2018-2-20  well known natural phenomenon in autogenous (AG) mills is the build-up of pebbles. Thesepebbles are typically called “critical size material” and occupy a large volume of the mill and thus reducethe capacity for new material to be processed. In addition to the mill volume reduction, the critical sizematerial is harder than the normal material and this contributes to additional power draw.
