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 ...

Rethinking the value of mill relining

Then, in the late 1980s when the price of copper rose quickly from a low of $0.62/lb to a high of $1.62/lb, this substantial increase in price further fuelled the industry demand for larger diameter SAG mills, with mill power quickly doubling from 15,000hp to 30,000hp (11,000-22,000kW). As SAG mills grew in size and number, so did the size …

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 ...
