Impact Crushers. What is an Impact Crusher? Impact size reduction incorporates striking to pulverize material. The primary types of impact crushers include -- horizontal shaft impactors (HSI), cage mill pulverizers, and vertical shaft impactors (VSI). Each impactor can be further designated as primary and secondary rotor crusher as well as tertiary and quaternary crushers.
The size reduction takes place quickly along short fracture lines, ... or jaw crushers that produce more slabby or flat material (5 to 1 length to height ratio). ... size reduction comes from the first impact with the rotor breaker bar.
Jaw crusher, Gyratory crusher, Impact Crushers, etc. b) Secondary crusher- The crushed rocks from primary crusher are sent to these secondary crushers for further size reduction.
