Bicycle Power for the Country Living Grain Mill | Sensible ...
The Country Living Mill has a handle with a radius of about 5 ½ inches. That's a 5 ½ inch long handle turning a 4 5/8 inch diameter grinding plate. Guess which one is easier to turn. But remember, it's a trade off. The Victorio is easier to turn, but you have to turn it a lot more times to grind the same amount of grain.

Mill (grinding) - Wikipedia
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Calculating Power Draw when sizing Ball Mills - Grinding ...
For instance a mill of 300tph with a 300% recirculating load would have 1200 tph going through effectively, but if we reduce the recirculating load to 200% at 900 tph it will not change the power calculation. However if we increase the fresh feed by 100 TPH the power calculation goes up as does the size of mill required.

High hardness materi-als become very abrasive; therefore, they are not suitable for high-speed hammer mills. In a typical jet mill, grinding action is caused mainly by particle-particle collisions, so wear to the mill's internals is less of an issue.
