Autogenous mill, Ag Mill, Semi-autogenous Mill, Ball Mill

Sometimes, in order to improve the processing capacity of the autogenous mill, a small number of steel balls can be appropriately added, usually accounting for 2-3% of the effective volume of the autogenous mill (also known as a semi-autogenous mill).

Autogenous and Semi-Autogenous Mills FLSmidth

Rely on our proven track record of SAG and AG Mill superiority. Since the early 1980s, 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 6-15% while autogenous grinding uses ore only.

Wet Semi-Autogenous Grinding Mills

The primary mill liner task force was formed in 1977. Its function was to improve the operating costs and milling efficiencies of the ten 8.2-m x 5.5-m (27 ft x 18 ft) wet SAG mills that were operating at the time. The SAG mills are driven by two 3500 HP motors drawing a total of 5450 kW at 76% of critical speed. In March 1981, a liner metallurgy change was made. The original liners were made

Mill (grinding) Wikipedia

SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in

Ball Mill VS Autogenous Mill-xinhai

But the autogenous mill does not need the steel ball or the steel rod to participate in the mill, only relies on the mineral itself as the medium, realizes the autogenous mill, therefore is suitable for the coarser material to sharpen. The autogenous mill can reduce the consumption of steel and thus reduce the impurity of iron in the material.
