The capacity depends on the feed size and the distribution. In general, a smaller feed size will result in a high capacity and, for a larger feed size, the opposite will apply. The rock size influence must be modelled in order to understand how it will affect the capacity and power in the VSI. 4.1. Modelling the mass flow into the crusher
The Knowledge Hub. Crushing chambers. Cone crusher basics in 4 minutes. This is the starting point for understanding how cone crushers work – and how they can make your mine or quarry more productive.

The product size distribution can be characterised by the size at which the% passing curve reaches specific percentage levels. The P20 (which measures the size …
All types of crushers are widely used in gravel and aggregate fields, and they are often put in use after the excavation and blasting processes. Although their common and basic function is reducing large size of rock into small size, they are applied to different crushing stages like primary, secondary, tertiary, quaternary stages.
This crusher reduces rock lumps from 2 m size down 25 mm. The crusher uses a single hammer rotor with peripheral speed of about 40 meters per second. ... of favorable size for feeding to grinding mills it is generally necessary to apply secondary crushing in another type crusher.
