Mill (grinding) - Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes. There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind (windmill) or water (watermill). In modern era, they are usually powered by electricity.

2017. 6. 3.  Fracture mechanics methods may also be used to obtain fatigue design criteria for mill structures. While these methods are more sophisticated, and better recognize the micromechanics of fatigue cracking than the previously described methods, they are harder to apply at present to more practical structures like mill shells with their attendant weldments in critical areas.

Structural Analysis and Condition Monitoring of Grinding Mills: A

2016. 10. 5.  Grinding mills are large rotating cylindrical steel vessels used to grind particles into finer pieces. The mills are important parts of the mineral enrichment process and the performed grinding is the last step of the comminution process, where the particle size is reduced by a combination of impact and abrasion. Grinding mills exist in a large variety of sizes and models for different types of grinding.

Grain mill structure for grinding cereals Britannica

2020. 8. 18.  Modern mills employ pairs of steel cylinders instead of wheels. For grinding into flour, wheat is ground between a series of cylinders, beginning with a set of grooved cylinders to break the grain open and ending with a final set of smooth cylinders to reduce the coarse meal to fine flour.
