Crushing & Screening Plant
The third step in crushing, or tertiary reduction, depends upon what is required. Two-inch or smaller pieces from the secondary crushers may be fed direct to stamps, rod mills, or ball mills, but it is more usual to use a third dry crusher to reduce the ore to ½- or 5/8-in. size before wet crushing, particularly in the case of ball milling.
