As shown in Fig. 2a, a large jaw crusher was used to reduce ore from the mine to an 80% passing size (P80) of 100-150 mm. A cone crusher was then used in closed circuit with a screen producing a 20-30 mm product which could then be fed with some added water into a tumbling mill filled with heavy steel rods (called a rod mill).
