They're crushing it Mine mesabitribune

At some iron ore plants, taconite is crushed down to pieces of small rock by primary, secondary and tertiary crushers. Some plants also use autogenous or semi-autogenous crushing, in which rock basically crushes other rock. Then, giant rotating mills which hold massive-size rods and balls, further grind the material.
