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 or water ().We recognize such "sizes" as 2x4, 2x6, 4x4, 1x2, etc. This measurement refers to the thickness and width of the lumber and the length varies. In reality, these measurements are not a true measurement of the lumber thickness or width. The true measurement of a 2x4 is actually about 1.5x3.5. When the board is first rough sawn from the log, it is ...
