SAG mills and AG mills have different definitions and operate differently. 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.
Figure 2: Rod Mill Ball Mills Description Ball mills are similar in concept to the rod mill but are charged with steel balls in place of the rods. The mill consists of a cylindrical drum, sometimes tapered at one end, and usually has a charge of steel balls (up to 40% by volume) ranging in size up to 125mm for larger mills.
It directly affects the grinding effect and the degree of refinement of the ore. When selecting ball mill steel balls, you need to consider the following factors: 1. The …
Grinding Balls for Ball mill and Sag mill in Mines: separating commercially valuable minerals, comminution and sizing ... mineral processing, also known as ore dressing, is the process of separating commercially valuable minerals from their ores.

A rod mill is a type of ore grinding equipment used to grind materials into fine powder. Unlike ball mills, rod mills use long steel rods instead of balls as the grinding medium.Rod mills are ideal for breaking down materials such as minerals and ores.
The ore is fed into the mill and as the cylinder rotates, the balls crush and grind the ore, causing the particles to break down in size. Rod Mills: Rod mills operate on the same principle as ball mills but use rotating rods instead of balls as the grinding media. The rods, which are typically made of steel, crush the ore as they rotate within ...
