Manual Burr Grinders
Manual burr grinders are turned by hand, rotating one grinding surface against the other. Coffee mills usually have a handle, providing leverage for the many turns required to grind enough coffee for a cup. The ground coffee is collected in a container which is part of the mill.
Salt, pepper, and spice mills, essentially the same as coffee mills, usually do not have a handle, the entire top rotating instead. While this is less convenient, only a few turns are required to grind enough. The ground product falls directly onto the food being seasoned; the mill has no container. A few mills have abrasive surfaces which do not rotate; each squeeze of the handles moves one flat plate past another, then the plates are restored to their original position by a spring. Many hard spices are available in containers incorporating a simple cone burr grinder, intended to be discarded when empty.
Most grinders can be adjusted to set the fineness of grind.
Manual mills can be used for grinding other food products than they are intended for. Be aware that mills designed for pepper grinding are inappropriate for grinding flour. However, coffee mills are a suitable substitute. Laura Ingalls Wilder's novel The Long Winter describes a family grinding wheat in a coffee mill to make flour during months of hardship.
Peugeot of France created the pepper grinder in 1842. The mechanism of case hardened steel cracks the peppercorns before the actual grinding process. The grooves on the Peugeot mechanism are individually cut into the metal and then case hardened, making them virtually indestructible. The Peugeot family history dates back to a mill in a small village in France around 1793. They have been manufacturing everything from tools to bicycles to peppermills and coffee grinders and much more for about 170 years.

Famous quotes containing the words manual and/or burr:
“Criticism is infested with the cant of materialism, which assumes that manual skill and activity is the first merit of all men, and disparages such as say and do not, overlooking the fact, that some men, namely, poets, are natural sayers, sent into the world to the end of expression, and confounds them with those whose province is action, but who quit to imitate the sayers.”
—Ralph Waldo Emerson (1803–1882)
“Heaven sometimes hedges a rare character about with ungainliness and odium, as the burr that protects the fruit.”
—Ralph Waldo Emerson (1803–1882)
