Ideally, the deck on the scalping screen should have a cut point equal to the closed side setting (CSS) of the crusher. The feed size to a secondary crusher is typically in the range of 50 mm to 250 mm (up to 300 mm). If the capacity is higher, the acceptable feed size gets larger. After crushing, the product is in the range of 0-60 mm (75 mm ...

a tertiary crusher (e.g. cone crusher) would produce. The reason is that the compressive force not only acts on the coarse end of the PSD, but throughout the particle bed on both coarse and fine particles, including the fine particles derived from the initially coarser fractions. A wide range of ores appear to generate products of a similar P80.
