Introduction: The ball mill is a tumbling mill that uses steel balls as grinding media. Ball mills can be used in wet or dry systems for bulk and continuous milling, and are most widely used in small or large-scale ore beneficiation plant. Dry grinding: suitable for materials that react with water, such as building stones such as cement and marble.

Alternatively, the iron ore minerals are liberated from gangue minerals by ball mill grinding, followed by hydro-cyclone, gravity concentration and magnetic separator. During the preparation of ore as a feed to blast furnace a significant amount of slimes (− 0.050 mm) are being generated (Rao 1985 ).

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

The breakage and liberation of minerals are the key to fluidized mining for minerals. In the ball milling process, steel balls function as not only a grinding action implementer but also energy carrier to determine the breakage behavior of ores and the production capacity of the mill. When ground products present a much coarse or much …

Rotary Scrubbers may range in diameter from 8' (2.5m) to 18' (5.0m) and lengths from 8' (2.5m) to 60' (18m) with aspect ratios (L/D) ranging from 1.8 to 3.0. Scrubbers can be sized to process up to 5,000 tph of ore. Improved washing can be accomplished by. Adjusting the water rate to the Scrubber.

A ball mill is a form of grinder that is used to blend or grind materials for use. It is a cylindrical device mainly for grinding material such as iron ores, ceramic raw materials, glass, steel, etc. The ball mill works on impact and attrition principle. Its impact is the size reduction given that the balls drop from almost the top of the shell.
