Secondary & Tertiary Crushing Circuits 911 Metallurgist
Almost all secondary and tertiary crushing circuits use the same type of crusher, the cone crusher. Within a secondary and crushing step. The output from the secondary crusher and the throughs from the secondary screen are transported by conveyor to the tertiary circuit, which includes a sizing screen 11.19.2 Crushed Stone Processing and Pulverized Mineral Processing

DEM-based design of feed chute to improve performance
The effect of feed chute design on tertiary cone crusher performance at the Sarcheshmeh copper complex was studied by an in-house developed DEM software called KMPC DEM ©. To simulate the overall crushing circuit, the multi-geometry procedure by improving the routines of object files importing into the simulation environment was Closed Circuit Reduction-Stage Capacities. Thus far we have considered open-circuit crushing through the several reductions in a multi-stage crushing plant. Very rarely are we able to turn out a finished product without closing the flow-line circuit somewhere along the line. Without going into any argument for or against closed-circuit Open or Closed Circuit Crushing 911 Metallurgist

Energy considerations in compressive and impact crushing of rock
1.2.. Production challenges in miningIn a typical mining application, a primary crusher reduces the size of blasted rock; from several hundred mm down to 0–250. mm.. A secondary crusher then reduces the size from those 250 mm down to about 0–70 mm, and is then followed by a tertiary crusher in closed circuit with a screen.The final To develop a crushing circuit it is useful to remember that the ranges of reduction ratios of crushers are • primary crusher 3:1 to 10:1, • secondary crusher 6:1 to 8:1, • tertiary crusher ≅ 10:1. Thus if a project requires a final product size of say 3 mm, then maximum feed size to tertiary crusher should be 30 mm.Gyratory and Cone Crusher ScienceDirect
