    The product shape is more easily controlled and energy is saved by the removal of particles once they have reached the size required. Large impact crushers will reduce 1.5 m top size ROM ore to 20 cm, at capacities of around 1500 t h 1, although units with capacities of 3000 t h 1 have been manufactured. Since they depend on high velocities for crushing, wear is greater than for jaw or gyratory crushers.
