Ball mills tumble iron or steel balls with the ore. The balls are initially 510 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.

In general, Most ball mills have two grinding methods wet grinding and dry grinding. Ball mill have been widely used in gold ore, silver mines, iron ore such as hematite and magnetite, common copper-lead-zinc mine processing line and ferrous metal mines such as molybdenum, tin, manganese and chromium.
Inside the ball mill, the crushed iron ore will grind the ore to about 0.2 mm with 3-inch steel balls. 3.This iron ore slurry is pumped to the agitation tank. This iron ore slurry is finally pumped to the flotation machine with the fine sulfide ore (-0.074 mm) going to froth flotation cells for recovery of iron.

A Ball Mill a type of grinder 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, flint pebbles and stainless steel balls.

Nov 01, 2017 An iron ore mill relies on the grinding and impact of grinding balls to complete iron ore crushing. The operating process of an iron ore mill is as follows first, the ores are poured into the mill, and both the ores and the grinding balls are lifted by the lifting bar arranged on the wall of the cylinder body to a certain height, after which they fall onto the bottom of the mill to complete the crushing.
Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 11and 1.81.
for green ball formation. Dry or wet grinding process is adopted for grinding the iron ore fines. In dry grinding process, equipment i.e. drier, ball mill, cyclones/bag filters, hot air generator recirculation fan, air slide, bucket elevator etc. are required. In wet grinding process, equipment i.e. ball mill, cyclones, slurry pumps, thickener, filter press, etc. are required.
