Rock Breaker

Rock breaker (rock crusher) is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. Rock breakers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

Crushing is the process of transferring a force amplified by mechanical advantage through a material made of molecules that bond together more strongly, and resist deformation more, than those in the material being crushed do.

Crushing devices hold material between two parallel or tangent solid surfaces, and apply sufficient force to bring the surfaces together to generate enough energy within the material being crushed so that its molecules separate from (fracturing), or change alignment in relation to (deformation), each other.

The typical rock breaker are :

JC Breaker

The JC series jaw crusher is the combination of the newest technology from Europe and SBM own decades’ experience and experiments. As an improved version, this series jaw crusher adopts “V” crushing cavity, making the feeding size equal to the theoretical one. Besides, the jaw plates are made tooth-shaped, which greatly increases the crushing efficiency.

JC Series Jaw breaker is made up of frame, the rotation part of the eccentric bearing,the working part of the crushing cavity, the safety unit and the adjustment devices of the discharging opening, and so on.

Spring Cone Breaker

With different applications, the Spring Cone Crusher can be divided into three kinds:standard type is for PYZ(second crush) ;middle type is for PYD(tertiary crush);short-head type is for primary and secondary crush . And its maximal resistance pressure is 300Mpa. A great team of engineers are always available to offer you best solutions with all sincerity.

The spring cone breaker consist of frame, transmission device, hollow eccentric shaft, bowl-shaped bearing, crushing cone, springs and hydraulic pressure station for adjusting discharge opening.
