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.
Primary Crushing:From Large to Medium
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 pruducing 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 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.
Tertiary Crushing:From Small to Smaller
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 crusher(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.
Impact Crushers are on the rise because they are the most versatile type crusher. They can process reasonable sized soft- medium-hard rock and can be used in concrete & asphalt recycle applications. A spinning rotor with hammers impacts the material and throws it against an impact wall (also called apron) which causes the material to shatter. As a result you get many different size cuboid particles that make high-quality aggregates.
