Meanwhile, Vale produced 320 million tons of iron ore during 2012, from which it generated $27.2 billion, 56% of total revenue. This indicates that the company sold its production for around $85 per ton, significantly lower than BHP. That said, we should keep in mind that the iron ore price was, on average much lower during 2012 than the first half of this year. Although Vale does not give detailed income figures on a divisional basis like BHP, Vale's annual report does show that the operating margin on ores produced was 49%. As iron ore accounted for 65% of the company's ores produced during 2012, we can assume that Vale's production cost per ton of iron ore produced was around $41.70 during 2012.

Drive mechanism: The means for turning the rollers can vary considerably. For the small amounts of grain a homebrew mill must crush, the simplest solution is to drive a mill using an ordinary crank handle. The small diameter of rollers on homebrew mills, however, may require a bit more patience during cranking sessions. Many people, especially those brewing large batches, attach a motor to speed up the process, giving them some extra time to savor the fruits of past labors. Some simply use a variable-speed drill, but many attach a small electric motor with belts and pulleys. Generally a ½- or ¾-HP motor is geared down with different-sized pulleys to run at rates between 200 and 300 rpm.
