Read MoreGyratory Crushers. The primary rock breaker most commonly used in large plants is the gyratory crusher, of which a typical section is shown in Fig. 5. It consists essentially of a gyrating crushing head (521) working inside a crushing bowl (522) which is fixed to the frame (501).
Read MoreAfter crushing in the jaw crusher, the output of the material of the jaw crusher is crushed again in the cone crusher to get the finer form of the same material. That is the reason this cone crusher is also known as the secondary crusher. The size of the final product you may expect is between the range of 35 mm to 350 mm.
Read MoreThe Crusher throw is defined as the distance in the direction of compression the moving crushing surfaces/plates travel from OSS to CSS. Throw = OSS – CSS. OSS and CSS will define a crusher's performance. The throw of the crusher is the distance that moving jaw moves in going from OSS to CSS. The capacity is a function of size and OSS.
Read MoreSecondary crushing, as you can imagine, is the second stage of material processing following its initial reduction. At this stage, material will flow through perhaps a second impactor or even a cone crusher, which is effective at breaking down these types of material. There are also tertiary and even quaternary stages of crushing that exist to ...
