SAG Mill Grinding Circuit Design

These mills typically grind ROM ore in a single stage. A large example of such a mill was converted from a single-stage milling application to a semi autogenous ball-mill-crushing circuit, and the application is well described. This refers to high-aspect AG/SAG mills. Ball Charge Motion inside a SAG Mill. With a higher density mill charge.

Combined DEM and SPH simulation of overflow ball mill …

A trommel is a rotary cylindrical structure that is rigidly attached to the discharge end of a mill. The intended operation of the trommel is shown schematically in Fig. 1.It contains moulded screen panels or wire mesh and can have different aperture configurations in each axial section depending on the intended duty.

SAG Mill Trommel Screens

The SAG mill trommel screen provides a simple mechanism to classify large volumes of mill product. Many designers and mill operators believe that the benefits of simplicity and the ability to handle throughputs in excess of 5 000 tph of solids make trommels the preferred equipment for this application.

Ball Mill Operation -Grinding Circuit Startup & Shutdown …

The grinding circuit operator must ensure that the ball mill runs properly loaded and gives the correct ore grind. A major practical indication of mill loading is the sound made by the mill. A properly loaded mill will have a deep rhythmic roar, while an under loaded mill will have a metallic rattling type noise and an overloaded mill will be …

Many designers and mill operators believe that the benefits of simplicity and the ability to handle throughputs in excess of 3 500 tons per hour of solids make trommels the preferred equipment for this application. "A …

How a Grate Discharge Ball Mill Works

Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG). How it works is, the slurry flows across the grate as it would a screen panel. On the other side of the grate/screens are veins like a pump impeller. As the mill turns/rotates the slurry is "pumped" out and discharged.

Trommel Screens

In simple words, a trommel is mining equipment comprising of a cylindrical drum that has many holes of a given size. The holes help in classification, and when the drum rotates it only lets the material smaller than the holes fall through while the rest of the material flows out of the other end of the trommel.
