The feed is limited to 1 to 1.5 meters in size. Thus, based on reduction ratio, the rock size is reduced to 10 to 15 cm. Typical reduction ratios are: Primary crusher: 3:1 to 10:1; Secondary crusher: 6:1 to 8:1; Tertiary crusher: 10:1 Therefore, if a 3 mm crusher product is required, maximum feed size to the secondary crusher would be 240 mm.
