The 19th century saw the invention of the slitting mill, however, a type of watermill that used hydro-power to automate slicing the iron into the nail's initial shape. Nailers were then relegated to the nail's final shaping, using a hammer to create the point and head.
The nailer would then hammer and work the iron shaft to create the final design of a nail. It wasn't until the turn of the 19th century when the slitting mill was pioneered. Using a slitting mill, metalworkers were able to mass-produce …

Hammer mills are widely utilized in agricultural, wood, mining . and chemical industry (Ebunilo, et al . 2010). In the hammer mills, HMHs design plays a significant role as the HMHs do most of the work. The factors taken into consideration while designing the HMHs are mass, general shape, the air paths created by hammer sweep, and heat treatment.
