There are different type crushers that achieve various objectives in material processing. Every application calls for a certain type crusher or a combination of multiple crushing stages to achieve a certain aggregate production goal.

A primary crusher provides an initial reduction in size. A mobile jaw crusher is considered a primary crusher in quarry operation. This stage aims at taking large chunks and bringing the material down efficiently to a consistent and manageable size for further processing through a secondary crusher. The material produced is not sought to be a final usable material.

Secondary crushers are designed to take a reasonable feed size and producing a final product size and adding a product shape. Common mobile secondary crusher types are horizontal shaft impact crushers (also referred to as an HSI) and cone crushers. When the feed material is not hard or big a secondary crusher can be used without a a primary jaw crusher. This is often the case in concrete recycling, limestone, shale, or sand & gravel applications. However, cone crushers - in most cases - will need a primary jaw crusher due to its infeed limits.
Taking small material and producing fines is very hard to do. For impact crushers it is easier to produce a 3/4"- out of a 25" rock than taking a crushed 1" feed and producing a 1/2" or even smaller product. A vertical shaft impact curhser (VSI) or a specialized horizontal shaft impact crusher with a grinding path (such as the RM V550OG! Mobile Impact Crusher) can be used to produce high amounts of fine material.
