SAG Mill Components. Once the basic operating conditions have been defined for the mill designer then, and only then, can he begin taking into account shell and head stresses and trunnion bearing sizes required to carry the load and to give the required openings for feeding and discharging the mills. Mill heads are key structural components …

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

A 42-ft SAG mill was designed and built for Minas Congas mine in Peru, but never installed. "The rise from 34- to 40-ft-dia. SAG mills was quick, but then stalled," Filidore explained. "Today, we're seeing a lot of 28-ft ball mills. Last month, we sold six 28-ft ball mills and six 40-ft SAG mills.

Traditionally, the number of shell lifters used in a SAG mill is equal to twice the number of the feet in the mill shell diameter (e.g., a 34-ft-diameter mill shell would have 68 shell …

The SAG mill (AG mill) has a large diameter and a small length. It looks like a flat round drum. The diameter of the SAG mill is generally about three times its length. The diameter of the hollow pivots at both ends of the barrel of a SAG mill is large. This SAG mill design can facilitate large-sized materials to enter the barrel smoothly.
