Esses Processes Of Open Circuit Crushing

Crushing occurs between two moving plates that are arranged to form an acute angle to apply a compressive force that results in tensile failure typically preferred for feed rates of 900 tph or less can be located underground or surface typically only a primary crusher operated in open circuit

In turn the product of a secondary crusher operating in open circuit is screened with oversize fed to a tertiary crushing circuit typically operating in closed circuit with screens variations or alternate configurations are common but the product of a typical tertiary crushing plant is nominally 100 passing 13 mm such circuits and their
