ENVIRONMENTAL ISSUES IN STONE CRUSHERS | The environmental
Emission during Crushing Operation . During crushing operation, generation of particulate emissions is inherent and the emissions are most apparent at crusher feed and discharge points. The greater the reduction in size during subsequent crushing stages from primary, secondary to tertiary crushing, the higher the emissions.

The objective of this project was to develop noise control designs for secondary crushers in taconite plants. The project included reducing the noise levels of the secondary crusher at the Jackson County Iron Company, such that the levels at 1 meter from the basic unit and 1 1/2 meters above the floor are 85 decibels, a-weighted network (dba).

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.

Crushing Plant Design and Layout Considerations
As it turned out, designers are now adding secondary or pebble crushers to SAG circuits, on both greenfield and retrofit projects, to increase feed rate to the SAG mill. In other words, crushing plants, from primary to quaternary circuits, are here to stay. There are three main steps in designing a good crushing plant: process design, equipment

Extracting top performance from secondary cone crushers
A secondary cone crusher achieves its best work when fines smaller than the desired crusher product are removed from the feed. When a crusher is operating with a full chamber, the nominal top size of the crusher discharge is about 1.6 times the closed side setting (CSS) of a top performing secondary cone crusher.
