Hammer mills are a type of impact mills that utilize fixed or swinging hardened steel hammers, chain or a cage. Hammer mills can be used for coarse crushing or fine grinding, depending on the size and configuration. Hammer mills are available in vertical and horizontal rotor configurations with one to many rows of hammers.
