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 ...

Mills: What are they? How are Mills used? Advantages
The phrase "ball mill" is used to define a grinding mill that has spherical balls inside. The length covered by the mill is equal to the diameter of the mill body. ... Rod mills require less steel than ball mills for a comparable grind because the media and ore make better contact at a reduced speed. Broken and damaged rods should be ...

SAG Mill Grinding Circuit Design
AG/SAG mills grind ore through impact breakage, attrition breakage, and abrasion of the ore serving as media. Autogenous circuits require an ore of suitable competency (or fractions within the ore of suitable competency) to serve as media. SAG circuits may employ low to relatively high ball charges (ranging from 2% to 22%, …

Effect of Water & Density on Grinding Mill
The more water that is added, the faster the ore will go through the mill. This means the time it has to be ground will be reduced and a poor grind will result. At the other extreme, if not enough water is used, the ore will not be able to flow through the mill. The result is the ore will not be able to move into the rod load. Because there isn ...

Grinding Media in Ball Mills for Mineral Processing
Ball sizes that are used in grinding should be large enough to break the largest and hardest ore particles. Optimal ball sizes depend on the feed/product size ratio, mill dimensions, and breakage kinetics parameters. Usually, larger balls grind coarser ore particles efficiently and smaller balls grind fine particles more efficiently . Larger ...
