Size Reduction – Visual Encyclopedia of Chemical Engineering
The hammer crusher, also called the hammer mill, is an example of an impact crusher. In hammer crushers, hammers swing freely on a disc mounted on the main shaft within the device. As the disc rotates, the feed material is struck and crushed by descending hammers until it is fine enough to pass through a screen or openings and exit the device.
