How Gear Ratios Work and Why They're Important
The gear ratio between gear 2 and gear 3 is then 1:2, so for every revolution gear 2 makes, gear 3 makes half a turn. So for every turn gear 1 makes, gear 3 makes about 0.29 turns (0.57/2). That results in a total reduction of the system of 3.45. Gear Ratios at Work. Gear ratios are especially important for complex systems, like the gears in ...

Understanding Rolling Process in Long Product Rolling Mill
Good figures for rod and bar mills are 90 % to 93 %, for structural mills, the good mill utilization figures are 75 % to 78 %. If a mill rolls 80 % of the calendar year, that is 365 x 24 x 0.80 = 7008 hours. If the mill rolls 800,000 tons per year, it runs at an average production rate of 114.16 tons/hour.

How Gear Ratios Work | HowStuffWorks
The gear train shown below has a higher gear ratio: In this train, the smaller gears are one-fifth the size of the larger gears. That means that if you connect the purple gear to a motor spinning at 100 rpm (revolutions per minute), the green gear will turn at a rate of 500 rpm and the pink gear will turn at a rate of 2,500 rpm.
