Pinyin of milling: niǎn yà.

Milling (niǎn yà) is a Chinese word meaning a round axle or wheel, etc., pressed against an object to turn it, and is recorded in People's Literature, No. 6, 1976: "He was hurrying his car toward the bridge, the peak of the torrents had just arrived, the The bridge pillars were not yet out of order. It was precisely after his heavy cart had run over and pressed on it that the pillars of the wooden bridge went askew."

Difference between grinding and rolling: different pronunciation, different meaning, different usage, different occasions of use.

1. Different pronunciations

Rolling is pronounced: niǎn yā. It also describes being dominant in some way relative to an opponent. (Wheels, etc.) Rolling over the ground. E.g. The wheels of the car rolled over the road day and night.

Rolling means that a round axle or wheel, etc., is pressed against an object and turned so as to crush it. It is rolling, not grinding. Because of the ancient rolling through grinding, so it will be written milling, but this is the wrong way to write, which is commonly known as the pass word.

3. Different Usage

Milling is often used in the highly destructive act of squeezing, which also refers to squeezing a person (opponent). Rolling, on the other hand, is often used to give treatment to grains and cereals.

4. Different occasions

Rolling and crushing are related to heavy machinery, but their occasions and effects are different. Rolling usually refers to the mechanical process of flattening or slicing an object into thin slices, while milling refers to the use of heavy machinery rolling on the ground or road to compact or flatten the surface.

Milling is usually applied in industrial production, such as steel, coal, non-ferrous metal industries. In these industries, mills are essential equipment. Mills can press large pieces of raw material into thin sheets or strips for further processing. During the rolling process, the material is subjected to tremendous pressure, so the design and maintenance of the mill is very important to ensure its stability and precision.
