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.

Ball Mill. The ball mill's basic concept dates back to prehistoric times when it was used to grind flint for pottery. A pharmaceutical ball mill is a type of grinder that is used to grind and combine materials in the production of different dosage forms. Impact reduces the size of the balls as they fall from near the top of the shell.
