Simulation of wet ball milling of iron ore at Carajas

2007-10-19  The mill was filled with a formal ball filling ( JT) of 0.2 volume fraction (20%) and rotated on a roller table at 70% of critical speed. The formal definition of J assumes that the porosity of the ball bed at rest in the mill is 0.4 so (1) Mass of balls = 0.6 J V ρ b where V is the mill volume.

Effect of planetary ball milling on phase

2011-4-10  Planetary ball milling induces phase transformation of silica-rich iron ore. Silica-rich iron ore is converted to fayalite in the presence of iron powder during milling. Formed fayalite is quite comparable to natural fayalite. Milling overcomes the natural conditions required for the formation of fayalite.

Simulation of wet ball milling of iron ore at Carajas

The technique was then extended to predict the behavior of a full-scale mill at a capacity of 308 metric tons/h and a circulating load of nearly 600%. Agreement between simulated results and plant test results was reasonable except that the simulator predicted a product (overflow) size distribution with a higher sharpness index than observed.

Reduction of iron-oxide by ball-milling with hydrogen

A new method for reducing iron-ore without greenhouse effect gas exhaust was developed to prevent the global warming. The reduction of α-Fe 2 O 3 (hematite) by ball-milling with hydrogen gas flow was studied by XRD, SEM, TEM and Moessbauer spectroscopy. Iron oxide (α-Fe 2 O 3) powder was charged into a container for ball-milling with stainless steel balls.
