energy consumption of gyratory crushers by using CSS and feed size variations. However, the feed fragmentation in this model is based on the Kuz-Ram model (Cunningham, 1983) and is assumed to be a function of burden and spacing, regardless of all other factors affecting blast fragmentation. In reality, it is well known that blast-induced ...

"The main inputs to the model are the in-situ block size (F80), the post-blast fragmentation (P80) and the intact tensile strength (To). The output from the model is the specific blast energy (ESE). Modern techniques are being used to obtain the input parameters for the sitespecific blast fragmentation model.

Gyratory crushers and cone crushers are two popular types of crushers used in the mining industry for crushing rock and other materials.
