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.
