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.

However the SAG route is more power-intensive and, for very hard ores, comes with some process risk in predicting performance. More recently, a hybrid solution has become available in the form of high pressure grinding rolls (HPGR's), which can replace the third stage of crushing and also the SAG mill.

Ball mill: When the particle size of the product is less than 0.5mm, the grinding effect of the ball mill is greater than that of a rod mill of the same specification. SAG mill: The SAG mill has a wide range of feeding particle sizes and can process larger minerals, but at the same time, its output particle size is relatively larger.

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.

AG, and Ball mills. Specifically designed for the SAG mill, a new device is presented that digitizes and processes vibration from three key points on the SAG mill. From these three real-time signals, it is possible to measure the volumetric material fill level in the mill and the …

SAG Mill Circuit Example — Gold Processing SAG mill circuit example for gold processing [image: (135-6-3)] AG/SAG Mill. AG/SAG mills are normally used to grind run-off-mine ore or primary crusher product. Wet grinding in an AG/SAG mill is accomplished in a slurry of 50 to 80 percent solids. 2D and 3D simulations of particles in a SAG Mill

The new Mill Filling Prediction (MFP) tool is a soft sensor (a mathematical model that act as a sensor) to provide information about the mill's contents and enable it to be controlled closer to its maximum capacity, it says. The MFP tool is developed by Dr Marko Hilden (pictured with Mohsen Yahyaei here), a Senior Researcher at JKMRC, who ...

Mill drive arrangement. Mill drives are generally located on the outside of the mill to facilitate maintenance. • Mill discharge arrangement. If the SAG and ball mills feed separate pump systems this is not an issue. If the two stages feed the same pump system, the …

In contrast to laboratory-scale testing for ball mills and AG/SAG mills, test work results for stirred mills can be used for sizing full-size equipment with a scale-up factor close to one. Larson et al .[ 19, 20 ] found a scale-up factor for the Isamill of exactly 1, while Gao et al .[ 8 ] imply that the scale-up factor for SMDs is 1.25.

SAG mills are primarily used at gold, copper and platinum mines where steel balls are used for the grinding. The Manta Controls Advanced Control System, called the SAG Cube, automatically monitors and controls a SAG Mill, keeping track of critical process variables impacting mill throughput.

SAG mills, rod mills and ball mills are the classical pieces of grinding equipment employed in gold recovery plants. There is an increasing trend to employ SAG mills (semiautogenous mills) in place of secondary and tertiary crushing and primary grinding. The most common type of rod mill is the overflow mill. There are two typed of ball mills used.

The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder. Rock is ground by the turning action of the mill, and impact from the hardened steel balls and the rock itself. In order to ensure that the rock is ground finely enough the SAG mill has a trommel screen (5), which acts like a large sieve.
