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 ().
in a condition to change its moisture content readily in the mill. In addition the added work done in the mill may generate enough heat to change the moisture content (Warner & Browne, 1963). Table A2.1.: Relationship between moisture loss or increase during grinding and moisture content during grinding.
used to clear grinding grain for measuring the fineness degree, mean weight diameter and size reduction ratio. Methods The hammer mill was evaluated at three sieve holes diameter (4, 6 and 8 mm) and three levels of corn moisture contents (10, 14 and 18% w.b).The mill productivity is determined by dividing the product mass by time; Mg/h.
