Open Circuit Crushing. In this sector on Secondary and Tertiary crushing, we will continue the practice of talking about different equipment, the work it does, and the effects of what I call operating variables. These variables are anything that affect the performance of the equipment. Lets begin with an over view of these two crushing stages.
3.2.1 Crushing Equipment Primary Crushers - Jaw and Gyratory Within the crushing circuit, a primary crusher reduces material down to a size that can be conveyed and fed to the secondary crushing circuit. The two most common primary crushers used for coarse run-of-mine material are the jaw and gyratory crushers.
A process audit at the Sarcheshmeh copper complex tertiary crushing circuit indicated that the crushing efficiency at this stage was lower than the target value. To initiate the standradzation process, the power data were transferred to the control room and the ultrasound level sensor was used to monitor the level of the material in the crushing…
MORE DETAILS: Secondary Tertiary Crushing Circuits. 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
Both open and closed circuit crushing is employed. For close circuit the product is screened with a mesh size much less than the set. Figure 6.4 is a typical set-up where ores crushed in primary and secondary crushers are further reduced in size by a rough roll crusher in an open circuit followed by finer size reduction in a closed circuit by a ...

Crushing is accomplished by compression of the ore against a rigid surface or by impact against a surface in a rigidly constrained motion path. Crushing is usually a dry process and carried out on ROM ore in succession of two or three stages, namely, by (1) primary, (2) secondary, and (3) tertiary crushers.
Eldorado also announced a 15-year mine life at its Kisladag open pit operation in Turkey after completing long-cycle heap leach tests and replacing the tertiary crushing circuit with a high-pressure grinding roll (HPGR) circuit.

The primary and secondary crushers would operate in open circuit, while the tertiary crusher would operate in closed circuit. During standard operation, the crushing circuit is designed to produce 6,000 tpd of feed to the grinding circuit at a particle size of P80 3/8 inch.
1. Primary crushing. As the first stage in a crushing circuit, primary crushing reduces material to a size and shape that can be handled by a secondary crusher. Typically, the minimum setting on most primary crushers is about 4 in. to 6 in. Jaw, gyratory and impact crushers are most often appropriate as primary crushers, although there can be ...
Apr 03, 2015 Crushers are classified into three types based upon the stage of crushing they accomplish. These are (i) primary crusher, (ii) secondary crusher, and (iii) tertiary crusher. The primary crusher receives material directly from run of mine (ROM) after blasting and produces the first reduction in

The number of crushing steps necessary to reduce ore to the proper size vary with the type of ore. Hard ores, including some copper, gold, iron, and molybdenum ores, may require as much as a tertiary crushing. Softer ores, such as some uranium, bauxite, and titanium/zirconium ores, require little or no crushing.
