Perfecting the Performance of Secondary Crushers | E & MJ

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

Jul 10, 2020 Secondary crushing, as you can imagine, is the second stage of material processing following its initial reduction. At this stage, material will flow through perhaps a second impactor or even a cone crusher, which is effective at breaking down these types of material. There are also tertiary and even quaternary stages of crushing that exist to

Jun 01, 2017 Jun 01, 2017 Effect of Secondary Crusher Feed Rate The influence of secondary crusher feed rate (i.e., feed to plant) on responses is shown in Figure 3-A. Standard settings were employed. The reduction ratio, the screen efficiency , and the % - inch material in screen undersize are virtually independent of feed rate over the range investigated

Oct 27, 2020 Oct 27, 2020 The secondary crusher must have a larger intake and do more work. The same reasoning will then apply to the third stage where it also will be fed with a coarser feed. In the end, to reach the required plant reduction, an extra crushing stage will be needed just because the reduction in the primary stage is insufficient

Typically, the minimum setting on most primary crushers will be about 4 to 6 inches, as noted above. Compression-style jaw, cone, impact crushers, and gyratory crushers are most often appropriate as primary crushing equipment types, though there can be overlap between primary and secondary crushers as far as suitable types. 2. Secondary Crushing
