Crushers and Their Types – IspatGuru

Crushers are classified into three types based upon the stage of crushing they accomplish. These are (i) primary crusher, (ii) secondary crusher, and (iii) tertiary crusher.

TECHNICAL NOTES 5 CRUSHERS

Cone crushers are commonly used for secondary, tertiary and quaternary crushing duties. Two variations are available

Jaw crushers reduce large rocks or ore by means of compression. Mechanical pres-sure is applied using the crusher’s two jaws; one is fixed while the other reciprocates. There are also primary and secondary types of these crushers. Jaw crushers are one of the most commonly preferred crushers due to their ability to crush all kinds of

Evaluation of blast fragmentation effects on jaw crusher

Primary crushers are large, rugged machines capable of handling large quantities of material and are used to reduce the size of blasted rock to sizes suitable for feeding secondary crushers. They typically handle feed sizes up to 1.5 meters with reduction ratios (ratio of particle feed size to product size) ranging from 3 to 10 (King 2001 ).
