A burr mill or burr grinder is a device to grind hard, small food products between two revolving abrasive surfaces separated by a distance usually set by the user. Usually the device includes a revolving screw that pushes the food through. It may be powered electrically or manually.
Devices with rapidly rotating blades which chop repeatedly (see food processor) are often described as grinders, but are not burr grinders. Burr mills do not heat the ground product by friction as much as blade grinders, and produce particles of a uniform size determined by the separation between the grinding surfaces.
Food burr mills are usually manufactured for a single purpose: coffee, pepper, coarse salt, spices, or poppy seeds, for example. Coffee mills are usually powered by electric motors; domestic pepper, salt, and spice mills, used to sprinkle a little seasoning on food, are usually operated manually, sometimes by a battery powered motor.
