Rod mills, how they function

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 1.4 to 1.6. Rod mills accept feed up to about

What is a ball mill? What are its uses and advantages

Ball mills are also often used on a laboratory scale to process ceramic materials. Milling a solid pellet (for example, following one sintering step and preceding a second) allows for better intermixing of the reagent materials and finer particulates with higher surface area (=> higher reaction rate) as opposed to using a hand

Mill (grinding) - Wikipedia

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.
