Answer. A millstone is a stone used to grind grain. When grain is milled, two stones are actually used: the bed stone, or base, which remains stationary; and the runner stone, which turns on top of the base, grinding the grain. In Bible times the millstone was a common item, and it is mentioned in several contexts in the Bible.

Jet mills operate in compressed air, gas or high pressure superheated steam. Jet mills have no moving parts, thereby eliminating contamination due to contact with external grinding media. It is also an ideal process to grind heat-sensitive and waxy material because no attritional heat is generated. Jet mill works on fluid energy.

The arc of contact in grinding is the portion of the circumference of the grinding wheel that is in contact with the workpiece. According to Foster, the longer the arc of contact, the more critical wetting becomes. "The correct velocity also is very important. A lot of people will flood the grinding area, but this is actually not beneficial.

When it comes to actually grinding your grains, you can choose from manual or electric mills. Manual grain mills are powered by a hand crank that you turn to grind grain between the plates. You don't need electricity to operate the mill, and the grains stay cooler because the plates don't move as quickly as those in an electric model.

Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation . The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved.

Feed mills receive incoming ingredients by both rail and truck (including hopper-bottom, bulk-solids and liquids trailers). Rail receiving hoppers should be designed to provide maximum capacity, but are usually relatively shallow, which constrains carrying volume.
