In the feed to the circuit only 10% of the material is below 1cm in size. The gyratory crusher will break 40% of the material above 1cm to below 1cm in size, while the cone crusher will break 50% of this material to below 1cm. The screen has a partition number of 0.8 for the larger particles and a partition number of 0.25 for the finer particles.

Inasmuch as these volumes pass the choke-point in the same time-period, the gyratory crusher capacity through the 13-14 zone is obviously the greater of the two. These two facts account for the superior performance of the standard gyratory and the standard jaw crusher when fitted with non-choking liners.

The primary crusher's function is to reduce the size of the rock or stone for easier handling and transportation. The primary crusher is usually a jaw crusher or a gyratory crusher, which operates by compressing the material between two surfaces. The jaw crusher works by moving the material between a fixed and a moving plate.

Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4 :1 and 9 : 1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3 :1 to 10 :1.
