A metate (or mealing stone) is a type or variety of quern, a ground stone tool used for processing grain and seeds. In traditional Mesoamerican cultures, metates are typically used by women who would grind nixtamalized maize and other organic materials during food preparation (e.g., making tortillas).
The flour exits from between the stones from the side. The stone casing prevents the flour from falling on the floor, instead it is taken to the meal spout from where it can be bagged or processed further. The runner stone is supported by the rind, a cross- shaped metal piece, on the spindle.
Quern stones were used in China at least 10,000 years ago to grind wheat into flour. The production of flour by rubbing wheat by hand took several hours. [8] Due to their form, dimensions, and the nature of the treatment of the surfaces, they reproduce precisely the most ancient implements used for grinding cereal grain into flour.
The milled grain (flour) is collected as it emerges through the grooves in the runner stone from the outer rim of the stones and is fed down a chute to be collected in sacks on the ground or "meal floor". A similar process is used for grains such as wheat, to make flour, and for maize, to make corn meal.
Iowa farmer Arthur Luscombe (1922–2008) [6] founded Art's Way Manufacturing in 1956 to produce and sell a power take-off powered grinder-mixer he had developed on his farm near Dolliver. By 1959, the business was manufacturing OEM grinder-mixers for Massey Ferguson, Owatonna / Gehl and International Harvester. [2]
In materials processing a grinder is a machine for producing fine particle size reduction through attrition and compressive forces at the grain size level. See also crusher for mechanisms producing larger particles. In general, grinding processes require a relatively large amount of energy; for this reason, an experimental method to measure the ...
