a SAG Mill limiting condition, i.e., harder ore, or a Ball Mill limiting condition, i.e., softer ore exists. For example, a ratio of 11.5 or up to 12 would indicate a trend away from processing harder ore types and an increasing bias toward processing softer ore types,
Jan 27, 2020 SAG mills generate higher levels of impact reduction and ball mills higher levels of abrading action. A mill lining system serves two purposes to protect the mill shell from wear caused by the impact and abrasion of the mill charge, and to elevate and tumble the mill contents in the necessary manner to create a grinding action.
Sep 03, 2014 Shell-mounted mills with end walls directly above the main bearings are generally stiffer than trunnion-mounted mills. We have checked this by comparing a 26 ft shell-mounted ball mill with a trunnion-mounted mill of equal grinding volume and same diameter. Detailed finite element models of each mill were created.

What s the Difference Between SAG Mill and Ball Mill . The feed of the ball mill contains grinding balls. In order to effectively reduce the direct impact of materials on the ball mill feed bushing and improve the service life of the ball mill feed bushing the feeding point of the groove in the feeding part of the ball mill must be as close to the side of the mill barrel as possible.
For example, the SAG mill may have 10 MW of power draw available and the two ball mills each of 7.5 MW of power draw available for a total of ratio of 1015 11.5. The software uses the particular power model BondBarratt, Morrell Mi, etc. to determine what is the transfer size where the ratio of E SAG to E ball matches the ratio of mill ...
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AGSAG mills 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 of a ball mill.
