- Large receiving opening per dollar of investment.
- Shape of receiving opening favourable for blocky feed. This, plus point 1, give the jaw a definite advantage over the gyratory, except in the very large sizes, for handling rock of massive formation.
- The jaw crusher is more easily adjusted, to compensate for wear of liners. This is particularly true in the larger sizes, and the range of adjustment is greater in all sizes.
- The jaw crusher does not lose any of its "new-condition" throw when the babbitt wears in the main, or in the pitman, bearings.
