WhatsApp: +86 18221755073Cone Crushers; Typically, the initial crushing stage is completed using either gyratory crushers or jaw crushers. It is often the case that there will be only one crusher installed, and this will be referred to as the primary crusher. Cone crushers are more often used for 2nd, 3rd & 4th stage crushing steps (although not always).

WhatsApp: +86 18221755073Jaw crushers are usually louder than cone crushers because of the back-and-forth motion of the movable jaw and the way the material slams against the crushing plates. Cone crushers, on the other hand, tend to be a bit quieter since the crushing action is more of a continuous, gradual process with less impact and not as much vibration.
WhatsApp: +86 18221755073impact crushing.
