The standard Hydrocone crusher operating modes rely on the ability to regulate the crusher CSS during crushing (Svensson et al., 1996). The setting mode (constant CSS) is the most commonly used operating mode in the aggregate production. CSS is however independent of size reduction and hence unable to regulate it.
