the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill power.
Nov 26, 2019 Both the autogenous grinding mill and the ball mill feed parts are welded with groove and embedded inner wear-resistant lining plate. As the sag mill does not contain grinding medium, the abrasion and impact on the equipment are relatively small. The feed of the ball mill contains grinding balls.
Oct 12, 2017 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.
Jan 11, 2018 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.
SAG milling extends itself to many applications due to the range of mill sizes available. They can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill and some or all of the work done by a ball mill. SAG mills are also an optimum solution for wet grinding since crushing and screening in these cases can be difficult, if not impossible.
