In Figure, hammer mill construction is shown. There are two types of hammer mill: horizontal and vertical shaft. Abrasionresistant materials are used for impact surfaces, such as haustellate or carboy, which are then coated with steel or stainless steel to make them abrasionresistant. Pharmaceuticals can be handled with stainless steel hammers.

A roller mill acts more like a cutting knife. As a roller spins, it creates a shearing effect. Roller mill particle size generally sees lower variance than hammer mills, which results in a more consistent grind. Hammer mills also use different screen sizes to adjust the particle size for either a coarser or finer grain.
