What’s the difference of Ball mill, SAG mill, AG mill?
Attrition mill is a type of grinding mill by kinds of media to crush lump to powderlike substances. The impact can be rock on rock such as in an Autogenous Grinding (AG) mill, rock and a small ball charge (~10%), used in Semi Autogenous Grinding (SAG) mills, balls of various sizes in Ball Mills and less commonly these days, steel rods in Rod Mills.
Ball Mill an overview ScienceDirect Topics
The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol
What's the Difference Between SAG Mill and Ball Mill
Ball mills are fine grinders, have horizontal ball mill and vertical ball mill, their cylinders are partially filled with steel balls, manganese balls, or ceramic balls. The material is ground to the required fineness by rotating the cylinder causing friction and impact.
Autogenous and SemiAutogenous Mills FLSmidth
Rely on our proven track record of SAG and AG Mill superiority. Since the early 1980s, we have been designing and manufacturing SemiAutogenous (SAG) and Autogenous (AG) Grinding Mills under the FullerTraylor brand. Semiautogenous grinding uses a minimal ball charge in the range of 615% while autogenous grinding uses ore only.
Difference Between Sag Mill vs Ball Mill mech4study
SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially.

and ball mills, have almost become obsolete in the move to higher milling rates required to process lower metal grades. Grinding circuits with fully autogenous (AG) or semiautogenous (SAG) mills, often combined with ball mills are now the standard to meet the high capacity requirement for processing ores with lower metal grades.
Processing Citic Pacific Mining
Each mill measures about 12 metres in diameter and has an internal volume of 1,220 cubic metres. As the AG mill turns, the ore crushes against itself and breaks apart. From the AG mills, the ore travels to the primary magnetic separators where the iron is drawn away from the waste material before it’s screened and fed into the ball mills.

ball charge, but not less than 18% of the total volume.” This states that AG mills are designed at 18% ball safety, mills operating at maximum 12% balls get 6% ball safety, while operations at maximum 18% get 3% ball safety. The original statement was that all mills should be designed at 3% ball safety over their maximum operating load.
