Bending is a forming process in which sheet metal is bent into the desired shape by applying bending stress. The sheet metal is bent so plastic deformation is reached. That prevents the metal from regaining its former shape. Air bending with a V-die. Parts such as flanges and corrugations are created by bending.

Fitzpatrick Hammer Mills produce the smaller PSDs and are more suited to abrasive and difficult to mill products. They are the mill of choice when you need to precisely control the particle size reduction process. It is important to get the feed throat angle matching the material characteristics - a vertical inlet for fragile material or horizontal for fine grinds.

The simplest form is a roll bend, which bends the work rolls convex or concave to work the center or edges, respectively. This gives the leveler the ability to remove center buckle and edge wave. With individual backup roll support adjustment, the work rolls can be shaped to increase or decrease the work in an area.
