Crushers are classified according to the stage of crushing which they accomplish, such as: 1) Primary; 2) Secondary; 3)Tertiary; A primary crusher receives the stone directly from a quarry after blasting, and produces the first reduction in size. The output of the primary crusher is fed to a secondary crusher, which further reduces the stone size.
Choosing secondary, tertiary and fine crushers. Cone crushers have long been the preferred choice for processing of hard or abrasive materials. This category …
Coarse crushing equipment: The commonly used equipment is jaw crusher. In the limestone crushing production line, the coarse crushing equipment can crush the large pieces of limestone mined into stones of 125-400mm in size. Medium crushing equipment: Commonly used equipment are impact crushers, fine crushers, etc.
Roll crushers can be used for both primary and secondary crushing, depending on the application. Hammer Mills: Hammer mills use rotating hammers to crush the mineral samples against a stationary grinding surface.

Cone crushers are commonly used for secondary crushing (although impact crushers are sometimes used), which typically reduces material to about 2.5 to 10 centimeters (1 to 4 inches). The material (throughs) from the second level of the screen bypasses the secondary crusher because it is sufficiently small for the last crushing step.
