Stone mill is a traditional tool for grinding grain. It usually consists of two stones, the lower stone is called "millstone" and the upper stone is called "millstone". The working principle of the stone mill is to put grain or other substances on the grinding disc by rotating the grinding disc above, and then grind it by gravity and friction.
Stone mill is a more modern tool for grinding grain. It usually consists of a pair of stones, one of which is fixed on the base and called "base stone" and the other is called "upper stone". The working principle of stone mill is to put grain or other substances into the middle gap by rotating stones, and then grind them by friction.
There are some differences between a stone mill and a stone mill. First of all, stone mills are usually more efficient than stone mills. Because of the different design and structure of the stone mill, it can grind grains or other materials more effectively, thus completing the work faster. Secondly, the stone mill may generate more heat during grinding. This is because the friction between the grinding disc and the stone mill is large, and the friction will generate heat. However, the stone mill adopts the method of rotary grinding, which has less friction, so it generates relatively less heat. Finally, there are some differences between stone mill and stone mill in grinding fineness. Stone mill can generally grind finer powder, while the particles crushed by stone mill are relatively larger.
Generally speaking, stone mill and stone mill are tools for grinding grains or other materials, but they are different in abrasive and grinding methods. Which tool to choose depends on the material to be ground and the user's personal preference.
