Secondary Tertiary Crushing Circuits - 911 Metallurgist

24/07/2015  This one involves both SECONDARY and TERTIARY crushing. This circuit is employed where either the tonnage or the work index of the ore is high enough to require that the crushing be done in stages. Again the ore will come from a Primary crusher and be scalped. The coarse material will be crushed by the secondary crusher. The fines will be taken out of the circuit. Once the secondary has finished with the ore

Open or Closed Circuit Crushing - 911 Metallurgist

29/02/2016  High-speed, short-throw crusher, such as the Type R or cone, will reduce practically all of its product to a one-way dimension not exceeding the close-side setting of the crusher; hence, in a closed-circuit operation, if the crusher-setting is anything less than the square-opening product size, practically all of the material will be crushed, (hiring the first pass, to a size which is less than the screen
