SAG mills usually have a larger diameter than length and are used to reduce large feed size ore (typically ~300mm) down to ~3mm, often for further grinding in a secondary process. Ball mills are smaller in diameter than length and can be used in either primary, secondary or tertiary grinding applications to reduce material from ~20mm to very fine product sizes measured in microns or mesh.

Ball mill external appearance and internal view. Ball mills are filled up to 40% with steel balls (with 3080 mm diameter), which effectively grind the ore. The material that is to be ground fills the voids between the balls. The tumbling balls capture the particles in ball/ball
Mining Glossary Ball Mill A steel cylinder containing about 40% volume of steel balls used to grind ore. The mill is rotated causing the balls to cascade and grind the ore. porous filter medium and filter out all fine solids from relatively clear feed solution. such as silver, copper and mercury, which will be further refined to near pure gold.

Feed. Both the autogenous grinding mill and the ball mill feed parts are welded with groove and embedded inner wearresistant lining plate. As the sag mill does not contain grinding medium, the abrasion and impact on the equipment are relatively small. The feed of the ball mill contains grinding

Tower mills, often called vertical mills, stirred mills or regrind mills, are a more efficient means of grinding material at smaller particle sizes, and can be used after ball mills in a grinding process. Like ball mills, grinding (steel) balls or pebbles are often added to stirred mills to help grind ore, however these mills contain a large screw mounted vertically to lift and grind material.

Ore Grinding Mills are used for the fine grinding as the last step in the reduction of an ore prior to concentration (gravity or flotation) or cyanidation. Practice varies, depending upon the type of ore and the amount of reduction required.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and 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, flint pebbles, and stainless steel balls.
influences the grinding efficiency. In iron ore, for instance, a variation of 2 to 3% solid content in the slurry could lead to a difference up to 10% on the energy (kWh/T) for a similar grind. Optimization of mill performance by using online ball and pulp measurements J o u r n a l P a p e r
#0183;#32;Grinding in a ball mill is influenced by the size of the grinding media, the speed of the mill, the size of the quantity and size of the feed and types of circuit used. In batch grinding, the particle size is continuously reduced with time but minerals of various complexities behave differently and studied to predict the product size with other influencing parameters.
#0183;#32;The effect of time of grinding in a ball mill has been studied covering a range of 4 min to 32 min. 50 g of feed with size, and cm were fed to the mill and run at the speed of 66 rpm. The number of balls of one inch size kept as constant at 100.
