A Semi-Autogenous Grinding (SAG) mill is a large, rotating cylindrical mill used in mining to grind ore, typically in conjunction with a ball mill, using a combination of steel balls and the ore itself as grinding media. 

Here’s a more detailed explanation:
    • Purpose:

      SAG mills are primarily used in the initial stages of ore processing to reduce large ore chunks into smaller, more manageable sizes, often before they are sent to ball mills for finer grinding. 

    • Grinding Media:

      SAG mills use a combination of steel balls and the ore itself as grinding media. The ore acts as a “natural” grinding media, with the steel balls assisting in the crushing process. 

  • Operation:

    The mill rotates, causing the grinding media to tumble and impact the ore, breaking it down into smaller particles. 

  • Size and Shape:

    SAG mills are typically large, cylindrical structures with a larger diameter and shorter length compared to ball mills. 

  • Closed Circuit:

    SAG mills often operate in a closed circuit with screens that size the ore and send it back to the mill for further grinding. 

  • Applications:

    SAG mills are commonly used in copper, iron ore, and gold mining operations.
