Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized by their large diameter and short length as compared to ball mills. The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the plates onto the rest of the ore charge.

The Difference Between the Ball Mill and Rod Mill. Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1 ...
In addition, the ratio between the length of the barrel and the diameter of the rod mill is generally 1.5-2.0, while the ball mill is relatively small, generally not more than 1. 2.Internal structure. The rod mill uses the steel rod with a diameter of 50-100mm as the grinding medium, while the ball mill uses the steel ball most.
the apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ ball mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where …

The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's crushing ratio is smaller. The feed size is usually between 20-30mm and the product size is 0-3mm. Feed Both the autogenous grinding mill and the ball mill feed parts are welded with groove and embedded inner wear-resistant lining plate.
Autogenous grinding mill: in this grinding mill, rotating drums throws in large balls of matter in a rapid motion. This causes the ball to break and make smaller particles. SAG mill: SAG is the short form of semi autogenous grinding. The difference between autogenous and SAG mills is, it uses balls to grind like ball grinding mill.
