SAG Mill - Semi-Autogenous Grinding Mill

A SAG mill is characterized by its large diameter and short length. It rotates, tumbling its contents violently, causing a breaking action. The mill is lined with wear resistant steel liners which are fitted with lifters to assist with raising the load. The liners are replaced as they wear and the lifting action has degraded.

How a Grate Discharge Ball Mill Works

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.
