The jaw crusher. Crushing is the first stage of size reduction of mined rocks. Primary crushers are heavy-duty machines, used to reduce the run-of-mine (ROM) ore down to a size suitable for easy handling. A line diagram of a double toggle jaw crusher and its main components is shown in figure 2. The jaws are set at an angle to each other.
