What is the difference between a SAG mill and ball mill?

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%. [6] [7] The largest SAG mill is 42′ (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor. [8] A SAG mill

What's the Difference Between SAG Mill and Ball Mill

2019-11-26  The working principle of the self-grinding machine is basically the same as the ball mill, the biggest difference is that the sag grinding machine uses the crushed material inside the cylinder as the grinding medium, the material constantly impacts and grinding to gradually pulverize.

Difference Between Sag Mill vs Ball Mill mech4study

2017-10-12  Ball mill is a fine grinder. A horizontal or vertical rotating cylinder which is filled partially with the balls of ceramics, small rocks and balls made from stainless steel. The ball charge of a SAG mill is about 29% to 30%. By friction and influence of tumbling balls inside rotating cylinder grinds the raw material to the

What’s the difference of Ball mill, SAG mill, AG mill?

2021-7-7  The Sag mill uses lifting plates along the interior of the drum, which lift material throughout the rotations, causing them to fall onto one another to promote crushing. A ball mill has many steel or porcelain balls put in a drum to grind the feed between balls and between the balls and drum inner wall as the drum rotates.

Dynamic modeling and simulation of a SAG mill

2018-10-1  The dynamic model of an AG/SAG mill includes several interlinked sub-process modules, and these modules can be updated individually. As shown in Fig. 1, the mill is divided into n sections, where m is the section number and q is the transported material. All sections have the same length, and each section contains a dataset of particle information at any simulating time step, such as size
