Crushing and grinding e Practice and problems in …

The ROM ore is crushed in two stages. The ore is fed directly from the mine shaft bin through an apron feeder and a conveyor belt to the primary (jaw) crusher which operates in closed circuit with a double deck vibrating screen (50 mm and 30 mm opennings). The crushed ore (-30 mm) is further reduced to —15 mm in a secondary (gyratory) crusher,
