Tests on grinding fineness show that, the optimal fineness of primary grinding and regrinding in the separation process of multi-stage grinding should be 65% -0.074mm and 90% -0.045mm, respectively. The produced iron concentrate can successfully reach 64.28% Fe and 0.42% S, respectively, with iron recovery of 53.62% and desulfurization rate of up to 90%.
Grinding takes place in more "open" space which makes the retention time longer and adjustable compared to crushers. Theoretical size reduction and power ranges for different grinding mills [image: (135-6-1)] AG/SAG Mills Autogenous Grinding (AG) Mill.

The regrinding cost will generally be only a small fraction of the primary grinding cost. Therefore, for this purpose, a lower order of accuracy is adequate in the case of regrinding. The general procedure is first to calculate the kilowatt-hour per ton for grinding the rougher concentrate resulting from each primary grind to 80 percent passing 50 microns, using Bond's …
Usually, the grinding circuit contains at least two interconnected mills with material classifiers (e.g. cyclones) separating the fine material from the coarse (that then goes for regrinding). The process is energy intensive with power consumption of roughly 20 to 30 MW and feed throughputs of 2,500 to 3,000 t/hr. Process variables are mill loads, motor torque and power, plus …

The most commonly used grinding media in regrinding duties is ½ inch diameter chrome steel balls and 10mm mild steel cylpebs media. For coarser grinding applications larger media is required. ISAMILL Development of ISAMILL (Figure 2) started in 1990 as a joint venture between Mount Isa Mines Limited and NETZCH – Feinmahltechnik .
The adoption of 's Vertimill grinding mills in Anglo American's Minas-Rio System resulted in a 30% reduction in electric power consumed during regrinding operations. The energy gain represents a financial savings of approximately Eur 5,5 million (R$23 million) per year (excluding taxes) – including energy costs, demand and charges related to the use of the regrinding circuit.
