The jaw crusher is more easily adjusted, to compensate for wear of liners.
4.5.1.1 Jaw crushers. Jaw crushers are comprised of a fixed plate and a moving plate. Coal is fed into the crushers and the moving plate crushes the particles against the immovable plate. The minimum gap between the plates can be adjusted to change the top size the particles are crushed to.
