Secondary Tertiary Crushing Circuits - 911 Metallurgist

2015-7-24  Our last schematic represents a CLOSED CIRCUIT. 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

Mongolia 1,000t/d Gold Mineral Processing Plant - Xinhai

Crushing stage: Three stages a closed-circuit crushing and screening stage. The jaw crusher was used for the coarse crushing. After the coarse crushing, the material was sent to the circular vibrating screen by the belt conveyor for screening I. The sieve material on the upper screen (+30mm) was sent to another jaw crusher for secondary crushing.

Crusher - an overview ScienceDirect Topics

If size reduction is not completed after secondary crushing because of extra-hard ore or in special cases where it is important to minimize the production of fines, tertiary recrushing is recommended using secondary crushers in a close circuit. The screen overflow of the secondary crusher is collected in a bin (Fig. 13.16) and transferred to the tertiary crusher through a conveyer belt in close circuit.
