It typically occurs in two or three stages, with primary crushing reducing ore sizes from 1.5m to 10-20cm using heavy-duty machines. Crushing can be done via open or closed circuits. Primary crushers, like jaw and gyratory crushers, are heavy-duty machines that reduce run of mine ore sizes for transport and feeding to secondary crushers.
