What's the Difference Between SAG Mill and Ball Mill

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 ...

SAG vs. AG Mills: Understanding the Key Differences

SAG mills use a combination of steel balls and rock particles as grinding media, while AG mills use only the ore itself. Both types of mills are used for grinding ore in mineral processing operations, but SAG mills are larger in size and can grind larger quantities of ore. AG mills, on the other hand, are smaller and are typically used for ...

Choosing a SAG Mill to Achieve Design Performance

It is an approximation or a best guess based on limited data. This equation is: y = 225 – 1.94 x (1) Where x = the load in the mill expressed as measured % by volume and y = kg/h of feed. This information is based on observed throughput reductions caused by loading the 3-ft. SAG mill to over 26% by volume.
