Ball Mill - an overview | ScienceDirect Topics

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.

Optimization of Solids Concentration in Iron Ore Ball ...

Important advances have been made in the last 60 years or so in the modeling of ball mills using mathematical formulas and models. One approach that has gained popularity is the population balance model, in particular, when coupled to the specific breakage rate function. The paper demonstrates the application of this methodology to optimize solids concentration in ball milling of an iron ore ...

Will HPGR replace SAG Mill and Vertimill displace Ball ...

To place a ball mill or a VERTIMILL directly on the HPGR product may work on soft iron ores but will not work well on harder ores that require over about 7 kWh/t to achieve a T80 of 1.7 mm. When hard minus 10 mm scats are present (referring to HPGR product), the ball mill efficiency is reduced.
