ORE GRINDING EQUIPMENT Most of the tonnage milled today is ground in one of the following types of equipment or a combination of two or more: ball mills, tube mills, rod mills, and stamps. Chilean mills and Huntington mills are used only in a few isolated cases today. BALL AND TUBE MILLS All types of Ore Grinding Mills that consist 
These terms must not be confused with differential grinding, which has to do with the relative grinding rates of two or more minerals in an ore. Rod Mills = Selective Grinding. Ball Mills = Non-Selective Grinding. Large Balls & Small Rods Compared. Is it better to use a grinding mill with large balls or will small rods?
A ball mill is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls and steel balls.

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.
 But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter.
The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry.
A Grinding Ball Mill is a type of grinder used to grind and blend materials for use in mineral processes A Grinding Ball mill works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
A rotating drum causes friction and attrition between steel rods and ore particles. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency.

Rod Mill is a grinding machine similar to a ball mill. The obvious difference between the two is the grinding medium. Rod mill is named for the medium of the steel rod. The latter's grinding medium is undoubtedly a steel ball. Both of them can be used for grinding various metal ore and non-metal ore.
Ball mill is the key equipment for re-crushing the materials after they are primarily crushed. Ball mill is widely used for the dry type or wet type grinding of all kinds of ores and other grindable materials in cement, silicate product, new building material, refractory, fertilizer, black and non-ferrous metals, and glass ceramic industry.
