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 ...

Mill heads are key structural components of any grinding mill. They must carry the load of the shell assembly, liners, media and material in process, and transmit it evenly to the trunnion bearings to assure smooth operation. …

Ore processing is a 24 hour operation. Ore is stockpiled at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added to raise its pH. Following crushing through a jaw crusher, the ore is fed into the semi autogenous grinding (SAG) mill along with water and steel balls.

a Sag Mill Working Principle: Motor through reducer drive disc rotation, the hot air from the inlet into the vertical mill, the material falls from the feed opening disc central centrifugal force, its material the millstones edge from the millstone central to moving on after disc annular groovewhen subjected to the grinding rollers of the ...

Control of -SemiAutogenous Grinding(SAG) mill weight is an example of an important process that exhibits many of these aspects. Maintaining the SAG mill weight at the optimum value is critical for achieving maximum grind rate efficiency and mill production (Powell, M.S., van der Westhuizen, A.P., & Mainza, A.N. 2009).

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 ...
