kwh/t=WI*(10/15 10/50) WI = kwh/ metric ton. Note:On your flow sheet, the feed of the second ball mill is the under flow of the cyclone.The F80 and P80 are obtained by a sieve size analysis of the ore sample respectively in the feed and in the product. This gives the mass fraction of the ore retained between successive sieve sizes.

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 ...
