What is the grinders?

The term "Grindstone" is used to describe two different things that are made of stone. In one sense, it is a grinding stone that spins on the central axes at different speed speed, designed for grinding and polishing. In another sense, Grindstone Mill, a specialized stone that is designed specifically for grain grinding. The grinders in question are usually clear from context; Both are also used to describe the feeling of burden or work as in "Keep your nose on grinding."

In the first sense, the grinding stone is a discus of a thick porous stone with an opening in the middle. The swivel axle can be mounted through the hole to turn the stone; It is common to mount the grinding stone on the bath or basin, so the administration is spread into an easy cleaning container rather than across the floor. Using an electric motor or foot pedal, it is possible to turn different speeds that change depending on the project. They can also be used to create a paint on something like Stone or Wood; GrindstOnes used for polishing usually have a very fine grain, because rough grains would have a project to blame rather than by polishing. Several grindstones are stored in many shops, allowing people to gradually finer grindstones to achieve the desired finished appearance.

Millstone is in fact one of a pair of large circular stones. Millstones are stacked on each other for the grinding process; Usually the lower stone rotates, while the upper stone remains stationary. The grain is poured through the hole in the upper mill and then ground between them, running down the groove in the stone like flour. The grain of flour can change using mills of different sizes and different speeds during the grinding process.

Many mills are reversible, designed for grinding a huge amount of grain at a time. Early mills were driven by animals used for stone or for water bikes, and therefore many historical flour mills are located near rivers. ArcHeological kicks have revealed early versions of the mills, suggesting that people have been acquainted with the basic steps for making flour for thousands of years. Most modern flour is more cut steel than stone soil; Some people feel that stone flour is better and are actively looking for them.
