Autogenous Grinding Information, Autogenous Mills use large particles of ore instead of steel or other balls for grinding media. Autogenous mills use large pieces of ore as grinding media. The grinding is facilitated in autogenous mills by attrition with limited grinding by impact. For an ore to successfully grind autogenously, the ore must be competent, and it must break along grain boundaries at the desired product size.
Sino Grinding Mineral Processing, 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 mix of media and ore rises and falls in the mill like clothes in a
Grinding Circuit - an overview ScienceDirect Topics, Autogenous grinding or semi-autogenous grinding mills can be operated in open or closed circuit. However, even in open circuit, a coarse classifier such as a trommel attached to the mill, or a vibrating screen can be used. The oversize material is recycled either externally or internally.
Rawmill ,It is a short, large-diameter semi-autogenous mill, typically containing 5% by volume of very large 30 mm grinding balls. Feed can be up to 250 mm, and the larger chunks produce much of the grinding action. The mill is air-swept, and the fines are carried away in the gas stream. Crushing and drying are efficient, but the product is coarse around 00 µm , and is usually re-ground in a .
Mill grinding - WikiMili, The Free Encyclopedia, Autogenous mill. Autogenous or autogenic mills are so-called due to the self-grinding of the ore: a rotating drum throws larger rocks of ore in a cascading motion which causes impact breakage of larger rocks and compressive grinding of finer particles.

Autogenous and Semi-Autogenous Mills FL , Since the early 980s, we have been designing and manufacturing Semi-Autogenous SAG and Autogenous AG Grinding Mills under the Fuller-Traylor brand. Semi-autogenous grinding uses a minimal ball charge in the range of 6- 5% while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge.
Flexible milling and grinding solutions that last FL , For the mining industry, our semi-autogenous SAG grinding mill uses a minimal ball charge in the range of 6- 5 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous AG grinding mills involve no grinding media as the ore itself acts as the grinding media.
