Jul 24, 2015 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 it will be reclassified by a second set of screens with the oversize going to the tertiary crusher.
Cone crushers are fed with pre-screened material from the primary crusher usually a jaw crusher or primary gyratory, and the secondary crusher should always, if possible, have a scalped feed. Ideally, the deck on the scalping screen should have a cut point equal to the closed side setting CSS of the crusher.

Impact crusher Impact crushers are typically used for hard and moderately abrasive stone. The primary impact crusher, also known as a primary breaker, has a reduction ratio of 201. Impact crushers are higher maintenance than a jaw, although are still considered low maintenance with regard to their tonnage rate and overall productivity.
Back to the primary setting. If you squeeze that down and close the gap up you will reduce your production. This is because you are reducing the volumetric capacity of the crusher. Make sure that when you are starting you open up the primary arm and give the crusher a chance to do its job, then start to play with the secondary and tertiary arms.

Figure 5.1 Schematic diagram of a crusher showingg the open- and closed-side settings. 5.1 Jaw and Gyratory Crushers. Jaw and gyratory crushers are used mostly for primary crushing. They are characterized by wide gape and narrow discharge and are designed to handle large quantities of material. The capacity of the crusher is determined by its size.
Apr 03, 2015 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 size. The output of the primary crusher is fed to a secondary crusher, which further reduces the size of the material.

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 roll crusher. Such circuits are chosen as the feed size to standard roll crushers normally does not exceed 50 mm.
To understand the difference between the crushing phases, typical examples include reducing topsize from 900 to 300 mm for primary, 300 to 100 mm for secondary, and under 5mm for fine crushing, such as manufactured sand.
