The two most common types are horizontal shaft impactors (HSI) and vertical shaft impactors (VSI). HSI crushers are designed for primary or secondary crushing applications and can produce a cubical product with high reduction ratios. They work by using a spinning rotor with large hammers attached to the outer edge.

4.4 Jaw Crusher Capacity Estimation. The capacity of jaw crushers is a measure of the mass or volume of crushed material produced in unit time of operation. The capacity is primarily a function of: 1. crusher design characteristics such as width and depth of the crushing chamber, 2. open and closed side settings, 3.

The big feed opening of the GP Secondary is indirectly benefitting the primary crusher, a jaw crusher in this example, which can be operated with a more open closed side setting (CSS). A larger CSS gives the jaw dies significantly longer lifetime, visibly smoother feed material flow and higher productivity for the plant.

Jaw Crushersare another excellent choice for primary crushing applications because they can accept the toughest, hardest, most abrasive materials. They can handle dry to slightly wet material that is not sticky. These types of compression crushers are best suited for heavy mining, quarried materials, sand and …

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 crusher 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 ...
