Minutes to Hours Converter - CalculatorSoup
To convert minutes to hours, divide the minutes by 60. To show an example and how it works mathematically, let's say we want to convert 195 minutes to hours. We multiply by [1 hr / 60 min] which is 1. The min unit cancels out and our result is in hr units. 195 min * [1 hr / 60 min] = 195/60 hr = 3.25 hr. (note that if you instead divide by [60 ...

How do we extract minerals? | U.S. Geological Survey
Large tabular-shaped ore bodies or ore bodies lying more than 1,000 feet (300 m) below the surface are generally mined underground as well. The rock is drilled and blasted, then moved to the surface by truck, belt conveyor, or elevator. Once at the surface, the material is sent to a mill to separate the ore from the waste rock.

Rod Mills, How Do They Work? - Mine Engineer
Rod Mills, How Do They Work? Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.

An ore charge is added to the drum, and as it rotates, friction between the tumbling rods breaks the ore down into finer particles. Although similar in operation, a rod mill is often more effective than a ball mill as it requires lower rotational speeds and less steel to achieve the same results.

A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.
