PARAMETER OPTIMIZATION OF LARGE SAG MILL LINER

The semiautogenous (SAG) mill grinds materials with steel balls as the grinding media, and is the main grinding equipment in industrial production. Liners are equipped in the internal of the SAG mills, which have the function of protecting the barrel and adjusting the trajectory of the medium.

SAG Mill Autogenous and SemiAutogenous

SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size

It must be proven at pilotscale that the coarse grinding media can survive in sufficient quantity to efficiently grind the finer rocks without producing a critical size build up. Similarly, the balance between pebbles extracted from an AG mill and

Semi Autogenous Grinding Mill an overview ScienceDirect

A high aspect SAG mill had an ID of 6.0. m and the length measured 4.0 m along the central line.. The mill was charged with ore having a S.G. of 2.65 and the load was 40% of the mill volume. The grinding media steel balls occupied 12.2 % of the mill volume.The mill was rotated at 75% of its critical speed, which was 12.9 rpm.Estimate:

Relationship between SAG mill power draw, bearing

During the grinding process, a complex physical and chemical system is formed owing to the intensive interaction and collision between ground minerals and grinding media, causing various changes

SAG Mill Control: It Shouldn’t be that Hard E & MJ

SAG mill control fundamentally means managing the load in the mill by adjusting the feed rate of ore to the mill and/or manipulating the rotational speed of the mill. The best way to measure load is to mount the mill on load cells. The load cells are calibrated to measure the total weight of water, grinding media (balls) and ore in the mill
