These machines are at the core of most construction and quarrying operations, and are one of the most used pieces of equipment onsite. They work after a crusher or an excavator, which feeds material into the screener for sorting. The purpose of a scalping screen is to pre-process material for different applications.
The secondary crusher has a size reduction ratio ranging from 3:1 to 5:1. The secondary crusher can be a cone crusher, impact crusher, or gyratory crusher, depending on the hardness, abrasiveness, and size of the materials. The cone crusher is the most common type of secondary crusher used in mining and quarrying operations.
Quarry operators commonly design fragmentation blasts for safety, economy, ease of use at the primary crusher, and even public relations, but they often forget about quality. The blast layout must be properly engineered, documented and adhered to for maximum consistency.

Tertiary cone crusher configurations typically work with a reduction ratio of 2.5:1 to 4:1. The reduction ratio is defined as the ratio of the feed size for which 80 per cent will pass (F80), divided by the product size for which 80 per cent will pass (P80). The reduction ratio for tough, high strength, damp material is restricted to the low ...

Successful application of a cone crusher within a crushing circuit is measured by the amount of material passing through the cone, the power draw of the machine, the size distribution of the products coming out of the circuit …
Cone crushers and jaw crushers both work by compression, reducing materials by squeezing them until they break apart. The benefit that cone crushers offer over jaw crushers is their ability to output a more cubical product similar to impact crushers. Cone crushers have traditionally been used as secondary and sometimes tertiary crushing stations.
