Mills priced below that range use metal burrs instead of stone. These burrs shred or cut the grain, produce higher temperature flour due to friction, and don't offer the nutritional and other benefits of stone referred to in this article. The history of stone milling is an interesting look at the economy's effect on nutrition.
Basalt is difficult to crush in actual crushing operation, or operational cost is higher than other types of rocks. In the design of the stone crushing plant, the lamination crushing principle is used as much as possible to reduce the wearing parts cost. Normally the basalt crushing production line combination includes the following,
Stone mills were powered by water or wind to grind the grain between two large stones. Stone mills were common throughout Europe and they were excellent for grinding soft wheat varieties. The grain is poured into a hole in the upper stone, called the runner, and is distributed across the bottom stone, called the sleeper.

It is supposed that the mills consisting of two grindstones appeared in ancient Egypt but the archaeological finds from 1000 BC at the Boden Lake in modern Switzerland and around Dresden and Leipzig in modern Germany also reported similar grinding stones [7, 12].Very important feature of this grinding instrument is a shift from impact (mortar and pestle) to frictional force as a source of ...
Grist for one's mill ~ Since wheat and corn are ground by 'teeth,' the grinding stones 'chew' the grist into flour; thus to 'chew' over something became a thought or idea to ponder. The daily grind ~ The repetitive nature of milling led to the concept of 'the daily (same old) grind.'. Run of the mill ~ The ordinary, daily grind.
